What Is My Curl Type? UK Curl Pattern Quiz and Complete Guide
Ishant Sharma
Knowing your curl type is the starting point for every product choice, every routine decision, and every styling technique you use. Without it, you are applying products designed for someone else's hair and wondering why nothing works. But most curl type guides, including the quizzes that rank at the top of Google, make two assumptions that do not hold for UK curl owners: that you are testing on product-free hair with no underlying buildup, and that you are in a stable humidity environment when you test. Neither of those is reliable in the UK.
This guide covers the full 2A to 4C curl type chart with real reference objects, how to identify your curl type at home in UK conditions, why UK hard water means your curl type test may be giving you the wrong answer, why porosity matters as much as pattern for choosing products, how curl type changes with hormones, damage, and seasons, and a complete PCH product-by-curl-type guide that matches every product in the range to the patterns that benefit from it most.
What Is a Curl Type and Why Does It Matter?
The curl type system was created by stylist Andre Walker in 1997 to classify hair textures into four numbered categories with A, B, and C subcategories within each. For textured hair, the relevant range runs from Type 2 (wavy) through Type 3 (curly) to Type 4 (coily). The number describes the general category of pattern. The letter describes the diameter of the curl or wave within that category. A is the widest and loosest diameter. B is medium. C is the tightest.
The Zenvy Beauty June 2026 curl type chart confirms the system is useful as a starting point, but not as a complete diagnostic tool. Two people with the same curl type letter can need completely different products if their porosity, density, and strand width differ. The type gives you the shape. Porosity tells you how moisture enters the strand. Density tells you how much product to use. Strand width tells you how heavy a product the hair can support without being weighed down. All four together give you the full picture that the letter alone cannot.
Before You Type Your Curls: The UK Hard Water Step No Quiz Mentions
The Pure Curls House specialist perspective: Every curl type quiz and guide assumes you are testing your actual hair. In the UK, two-thirds of England is in a hard water zone where calcium and magnesium mineral deposits accumulate on the cuticle surface with every wash. These deposits do not just cause frizz and dryness. They physically change how the curl pattern expresses itself.
Mineral deposits add weight to each strand by bonding to the cuticle surface. This weight pulls curls downward, stretching coil diameter, flattening S-waves, and in some cases completely suppressing a pattern that should be tighter. A Type 3A curl coated in calcium and magnesium deposits may express itself as a loose 2C wave. A Type 3B pattern may look like a 3A. A genuine 3C may resemble a 2C curl with no visible ringlet structure. This means UK curl owners testing their type without first chelating are frequently typing the mineral deposit layer rather than their actual genetic pattern.
The correct UK approach before any curl type test: use the Rosemary Root Stimulating Shampoo Bar to chelate, removing the mineral layer. Then do the wash-and-air-dry test on completely clean, mineral-free hair. The curl pattern you see after chelating is your actual curl type. Many UK curl owners discover a tighter pattern than they thought they had.
How to Find Your Curl Type at Home: The Step-by-Step Method for UK Conditions
Chelate or Clarify First to Get Accurate Results
For UK curl owners who have not chelated in the past month, start with the Rosemary Root Stimulating Shampoo Bar. This removes the calcium and magnesium mineral deposit layer from UK hard water that distorts the curl pattern test. If you have chelated recently, start with a regular sulphate-free cleanse. The Treatwell February 2026 UK hair type guide recommends washing with a clarifying shampoo before typing, but for UK users, this needs to be a chelating cleanse specifically, not just a clarifying one, since clarifying removes product buildup but cannot remove mineral deposits. For London, Kent, Essex, and south-east England, where water hardness regularly exceeds 300 PPM, this chelating step is the most important preparation for an accurate curl type test.
Choose the Right Day: The UK Humidity Variable
This is the step that no other curl type guide mentions for UK conditions. UK outdoor humidity ranges from below 50 percent on a dry winter day to above 85 percent after rain or in summer. Your curl pattern air-dries differently at each end of that range because humidity changes how quickly each section of each strand dries, which changes how much the hydrogen bond pattern reforms as the hair dries.
For the most consistent curl type result, test on a typical UK day with relative humidity between 55 and 70 percent. An app like Weather Underground or the Met Office app shows current outdoor relative humidity. Avoid testing on a day that has just had rain (humidity above 80 percent can make curl patterns look tighter than they are) and avoid testing in the dry indoor heating season on a very cold, crisp day (humidity below 45 percent can make patterns look looser). Spring days in April or May typically offer the most stable UK conditions for curl type testing.
Air Dry Completely With No Products and No Touching
After chelating or clarifying, rinse completely and squeeze out excess water with your hands. Do not apply any product, conditioner, oil, or leave-in. Do not use a diffuser. Do not touch, scrunch, or manipulate the hair in any way. Blot lightly with a microfibre towel or plain cotton t-shirt to remove dripping water, then leave completely alone until the hair is 100 percent dry. For most UK curl types, this takes 4 to 8 hours. The pattern that forms during natural air drying with no product input is your natural curl type. It should not be assessed while any section is still damp.
Identify Your Pattern Using Reference Objects
Once fully dry, take a single strand from the crown of the head, a strand from the nape, and a strand from each side. Compare the natural curl formed in each strand to the reference objects below. Most UK curl owners find 2 to 3 different patterns across their head. This is completely normal, not a sign of damage. The Zenvy Beauty chart confirms that the majority of people have at least two adjacent pattern types across different head zones.
When multiple patterns exist, identify your dominant pattern (covering the most surface area) as your curl type for product selection purposes. Use slightly less of each product on the looser sections and slightly more on the tighter sections. The curl quiz at thepurecurlshouse.com/pages/quiz accounts for mixed pattern types in its product recommendations.
Test Strand Width, Density, and Porosity
Your curl type letter gives you the shape. Three additional characteristics give you the full picture needed for product selection. Strand width: Take a single strand and hold it up to a piece of sewing thread. Finer than thread are fine strands. Similar to the thread is medium. Noticeably thicker or wirier is coarse. Fine strands get weighed down by any product that is heavier than the strand can support. Coarse strands need richer products to absorb adequately. Density: In front of a mirror with dry, loose hair, can you see your scalp without parting? The immediately visible scalp is of low density. Visible with slight effort is medium density. Not visible without actively parting is high density. High-density hair needs more product volume per application. Porosity: slide two fingers from tip to root along a clean, dry strand. Smooth glide is low porosity. Slight roughness or catch is medium to high porosity. For a more complete guide to each of these, the hair porosity UK guide covers all three tests in detail, alongside the UK hard water's effect on porosity readings.
The Full 2A to 4C Curl Type Chart: What Each Pattern Looks Like
Type 2: Wavy Hair (2A, 2B, 2C)
Type 2 hair bends but does not loop back on itself to form a complete coil. The pattern is an S-shape that travels along the length of the strand. In the Zenvy Beauty June 2026 curl type chart, Type 2 follicles are described as slightly oval rather than round, which produces an S-wave instead of a true spiral. Wavy hair sits between straight and curly on the texture spectrum. Its unique care challenge is weight sensitivity: products that work well for Type 3 curls are usually too heavy for Type 2 waves and flatten them rather than defining them.
2A: Loose Beach Wave
Very gentle S-bends, often appearing almost straight at the roots with subtle movement at the mid-lengths and ends. Coil diameter 25 to 30mm. Shrinkage under 15 percent. The most common Type 2 subtype in the UK.
The main challenge is the definition without weight. 2A waves are fine and easily flattened by any product heavier than a lightweight leave-in. Frizz appears at the canopy layer rather than throughout the wave.
Reference: coil diameter of a 2 pence coin or wider
2B: Defined S-Wave
More pronounced S-bends starting from the mid-length down, with relatively straight roots. Coil diameter 18 to 25mm. Shrinkage 10 to 20 percent. The second most common Type 2 subtype in the UK.
The main challenge is canopy frizz at the top layer, while the underneath sections hold wave definition. Layering technique matters more than product quantity for 2B. Lightweight products used correctly outperform heavy products in this type.
Reference: barrel of a permanent marker
2C: Strong S-Wave to Near-Curl
Well-defined S-waves from the root, occasionally forming loose spirals at the ends. Coil diameter 14 to 18mm. Shrinkage 20 to 30 percent. Often misidentified as 3A.
The main challenge is the borderline nature of 2C: too much product pushes it toward a weighed-down, wavy look, too little product loses the definition that 2C is capable of. Medium-weight products applied to soaking-wet hair work best.
Reference: barrel of a Sharpie marker
Type 3: Curly Hair (3A, 3B, 3C)
Type 3 hair forms defined spiral loops that spring back when pulled. This is the transition from wave to true curl. Follicles are more elliptical than Type 2, and the resulting loop structure means that natural scalp oils cannot travel down the strand as effectively as they can on straighter types. Type 3 hair is prone to dryness at the mid-lengths and ends regardless of scalp oil production. Shrinkage is a significant feature of Type 3 hair and is not a sign of damage. The Boucleme April 2025 guide confirms that Type 3C hair commonly shrinks by 40 to 50 percent of its stretched length when dry, which is entirely normal.
3A: Loose Springy Spirals
Large, loose spiral loops with bounce and shine. Coil diameter 10 to 16mm. Shrinkage 20 to 35 percent. Andre Walker's original 1997 definition used "sidewalk chalk diameter" as the reference for 3A.
The main challenge is volume loss by midday. 3A spirals lose bounce as the day progresses without adequate hold. A medium-weight film-former at the styling step maintains definition longer than a pure moisture product would. UK summer humidity tends to increase 3A's frizz reactivity significantly.
Reference: a piece of sidewalk chalk
3B: Springy Ringlets
Well-defined ringlets with medium-tight coils and significant body. Coil diameter 6 to 10mm. Shrinkage 35 to 50 percent. High density (240 to 300 hairs per cm squared) is common in 3B.
The main challenge is dryness and tangling. The tighter coil structure reduces natural oil travel further than 3A. Deep conditioning weekly is non-negotiable for 3B. The definition holds naturally if the hair is left alone during drying, which is why the hands-off rule matters most for this type.
Reference: a standard pencil
3C: Tight Corkscrew Curls
Dense, tightly packed corkscrew curls. Coil diameter 5 to 8mm. Shrinkage 45 to 60 percent. 3C sits closest to the border with Type 4, and many people have both 3C and 4A patterns on the same head.
The main challenge is significant shrinkage and dryness. 3C needs richer products than 3A or 3B and benefits from working in sections rather than applying the product all over. Applying a rich styling product to each section individually ensures even distribution in the dense coil structure.
Reference: a drinking straw
Type 4: Coily Hair (4A, 4B, 4C)
Type 4 hair features tightly packed coils that spring directly from the scalp. Follicles are significantly flattened in cross-section, producing coil diameters much smaller than Type 3 and shrinkage that can hide 65 to 75 percent of the true strand length when dry. The Cocomera April 2026 European curl type guide confirms that Type 4 hair has the greatest difficulty retaining moisture of any pattern, because the tight coil structure creates the maximum number of cuticle bends per centimetre of strand, each of which is a potential moisture escape point and frizz entry point. Deep conditioning, protective styling, and the LOC or LCO layering method are foundational for all Type 4 subtypes.
4A: Defined Tight S-Coils
Tight, springy S-coils with visible definition. Coil diameter 4 to 6mm. Shrinkage around 50 percent. 4A retains some shine and is the most defined of the three Type 4 subtypes.
The main challenge is maintaining definition while providing enough moisture. 4A can tolerate richer products than Type 3 without being weighed down, and the LOC method (liquid, oil, cream) is effective for this subtype. Protective styling reduces the daily manipulation that causes breakage at the tight bend points.
Reference: a crochet or knitting needle
4B: Z-Pattern Coils
Sharp Z-pattern angular bends rather than round coils. No defined coil shape. Coil diameter varies. Shrinkage 60 to 70 percent. 4B is the most frequently mis-typed pattern: many 4B wearers are told they have 4C when they do not.
The main challenge is moisture retention and fragility at the Z-bend points. 4B is the most fragile Type 4 subtype structurally because the sharp angular bends create mechanical stress points under daily manipulation. Protective styling, gentle detangling on thoroughly conditioned wet hair, and minimal daily manipulation are the highest-impact care choices.
Reference: sharp angular Z-bends visible when the strand is stretched
4C: Ultra-Tight Densely Packed Coils
Extremely tight coils packed so densely that the hair reads as a single mass when dry. Coil diameter 3 to 4mm. Shrinkage 65 to 75 percent. 4C is the least defined and most fragile of all curl types.
The main challenge is extreme shrinkage, moisture retention, and fragility. 4C needs more moisture more frequently than any other pattern. Stretching techniques (banding, twist-outs) make the true length visible. Deep conditioning twice weekly is not excessive for 4C. The heaviest, richest products in any range are appropriate here.
Reference: coils tighter than a crochet needle often appear patternless without moisture
What Pure Curls House customers say about their curls
Verified purchase reviews from Judge.me
"I only discovered I had curly hair in my 40s. Since using these products, my curls are defined and hydrated, and I am no longer fighting my hair. The shampoo bar lathers beautifully, even in our hard water area, and my scalp has never felt cleaner. I wish I had started this routine years ago."
"I have been on the curly journey for about three months, and these products have been the turning point. The curl cream, in particular, is unlike anything I have tried before. It defines without crunch, and my second and third day curls are still bouncy. The whole routine feels lightweight and luxurious."
"For the first time in 30 years, I have found a product that works with my curls. It leaves them soft, and even after 4 to 5 days, it is still looking curly. I just top it up by putting a bit more product through. The moisture stays rather than disappearing the same day."
"I have type 2b/2c, and for years nothing worked properly. Once I switched to lightweight products and stopped layering heavy creams, I finally have full volume, wonderful, defined waves. I only use a small amount on soaking wet hair and scrunch. Total game changer."
Why Curl Type Alone Is Not Enough: How Porosity Changes Everything
Curl type tells you the shape. Porosity tells you how moisture enters and leaves the strand. Two people with the same 3B curl pattern can have completely different product needs if one has low porosity (tightly closed cuticle that resists moisture entry, needs heat during conditioning and lightweight products) and one has high porosity (raised or damaged cuticle that absorbs moisture rapidly but cannot retain it, needs richer products and protein support). Ignoring porosity when choosing products for your curl type is the single most common reason routines that should work do not.
Boucleme's guide on curl types confirms the point directly: your curl type does not determine how products affect your hair. It is actually all about the condition of your hair, how it absorbs products, and what ingredients it needs to thrive. The Zenvy Beauty AI Hair Analyser pairs curl type with porosity, density, and UK climate input for this reason, because pattern alone cannot produce a reliable product recommendation.
For UK curl owners specifically, porosity readings are often distorted by hard water mineral buildup in the same way that curl type readings are. A low porosity strand coated in calcium deposits can behave like high porosity (products seem to absorb then disappear quickly because they are being repelled by the mineral layer before reaching the cuticle), and a truly high porosity strand can seem to have product build up on it (because the mineral layer creates an outer coating that feels like buildup). Chelating before testing porosity produces a more accurate reading, just as it does before testing curl type. The full porosity testing guide is in the hair porosity curly hair UK guide.
When Curl Type Changes: Hormones, Damage, and the UK Seasons
Curl type is genetically determined by follicle shape and does not change permanently. But the expression of that genetic pattern changes under several conditions that UK curl owners commonly encounter. Understanding these helps you avoid the mistake of re-typing your hair every time it behaves slightly differently and changing your entire product routine in response.
Post-Pregnancy and Hormonal Curl Changes
Hormonal shifts during and after pregnancy change the hair growth cycle significantly. During pregnancy, the extended anagen (growth) phase produces more consistent, sometimes tighter-looking curl definition than the individual's baseline. Post-partum hormonal drops cause significant shedding of the telogen (resting) hair that accumulated during pregnancy, and the new growth that comes in during the recovery period is sometimes a different texture than the pre-pregnancy pattern. The Zenvy Beauty curl archetype guide confirms this is common: post-partum changes can move someone from 2C to 3B or vice versa, and the guide recommends re-testing quarterly during the first year post-partum rather than assuming the same pattern throughout. The PCH curl quiz at thepurecurlshouse.com/pages/quiz is suitable for re-testing at any stage because it asks about current behaviour rather than assumed type.
Chemical Damage and Curl Pattern Loosening
Bleaching, colouring, and chemical relaxing all change the disulphide bond network inside the hair cortex. Disulphide bonds determine the permanent curl shape. Bleaching oxidizes and breaks some of these bonds, which permanently loosen the curl pattern in the affected sections. This is not the same as the hair type changing. It is the permanent curl structure in the bleached length being altered. New growth that comes in from the scalp after bleaching carries the original genetic pattern, which is why bleached curls often have looser, more damaged sections alongside tighter-looking new growth at the roots. When typing bleached or colour-treated curls, be aware that the bleached sections may show a looser pattern than the true genetic type. Protein treatments like the PurePep peptide system in the Superfood Hydra Curl Conditioner provide temporary structural reinforcement to bleached sections that can partially restore definition, though permanent chemical alterations to the disulphide bond network cannot be fully reversed by conditioning alone.
UK Winter Curl Pattern Suppression
UK indoor central heating during October to March reduces indoor relative humidity to 30 to 40 percent. In this very dry environment, each strand contracts slightly as it dries because the strand is releasing more moisture than it would in higher ambient humidity. This contraction can tighten apparent curl diameter in some curl types and make hair feel more defined in winter than in summer. Conversely, UK summer outdoor humidity at 75 to 85 percent means the strand absorbs more atmospheric moisture during air drying, which can make curl clumps expand and appear looser than in winter. This humidity-based seasonal variation in apparent curl diameter is not a change in curl type. It is a normal mechanical response to humidity that the hydrogen bond framework responds to at every drying cycle.
PCH Products by Curl Type: What Works Best for Each Pattern
| Curl Type | Primary Challenge | Best PCH Product(s) | Key Reason |
|---|---|---|---|
| 2A Wavy | Definition without weight; flat roots | All in 1 Curl Cream (small amount); PurePep Conditioner | Phytocurl film-former defines without emollient weight that flattens 2A. Very small amount on soaking-wet hair only. |
| 2B Wavy | Canopy frizz; inconsistent wave pattern | All in 1 Curl Cream; Mint Ayurvedic Oil (finishing) | Phytocurl film-former groups wave clumps. Finishing oil addresses canopy flyaways without adding weight to the underneath. |
| 2C Wavy | Borderline definition; frizz-prone; UK humidity reactive | All in 1 Curl Cream; Cocoa Vanilla Bar (weekly wash) | 2C needs more film-former than 2A/2B but not as heavy as Type 3 products. The Phytocurl formula sits in the correct weight range. |
| 3A Curly | Volume loss by midday; moderate frizz | All in 1 Curl Cream; PurePep Conditioner; Butter Treatment (weekly) | The Phytocurl film-former extends hold for 3A longer than a pure moisture product. Weekly deep conditioning prevents the dryness that causes 3A to lose definition by the afternoon. |
| 3B Curly | Dryness; tangling; frizz throughout | All in 1 Curl Cream; PurePep Conditioner; Butter Treatment; Rosemary Oil | 3B uses the full PCH routine. Pre-wash Rosemary Oil reduces hygral swelling frizz. PurePep peptides reinforce the cortex bonds at the tighter coil bend points, where 3B is most vulnerable. |
| 3C Curly | Significant shrinkage; dryness; section-by-section application needed | Plant Peptide Butter Cream; Butter Treatment; Rosemary Oil | 3C benefits from the richer Plant Peptide Butter Cream rather than the curl cream. The denser coil structure absorbs more product per centimetre of strand than 3A or 3B. |
| 4A Coily | Moisture retention; protective styling essential | Plant Peptide Butter Cream; Butter Treatment; Mint Oil; Rosemary Oil | 4A uses the LOC method: Liquid (water-based leave-in or PurePep Conditioner), Oil (Rosemary or Mint), Cream (Butter Cream). This layering traps moisture at three levels for all-day retention. |
| 4B Coily | Moisture; fragility at Z-bend points; detangling | Plant Peptide Butter Cream; Butter Treatment (twice weekly); Scalp Brush | 4B needs the richest products in any routine. The Scalp Massager assists gentle cleansing without mechanical stress on the fragile Z-bend points. Deep conditioning twice weekly. |
| 4C Coily | Extreme shrinkage; extreme dryness; highest fragility | Plant Peptide Butter Cream; Butter Treatment (twice weekly); Rosemary Oil; Hair Supplement | 4C uses the richest combination of all PCH products. The Hair Supplement provides internal nutritional support that surface products cannot reach, supporting new growth quality in the UK, where vitamin D deficiency reduces follicle output in winter. |
| All Types (UK Hard Water) | Mineral deposit layer masking true curl type and blocking all products | Rosemary Root Stimulating Shampoo Bar (monthly chelating) | Non-optional for all UK curl types. Without monthly chelating, mineral deposits accumulate and prevent products from reaching the cuticle, regardless of how well the routine is otherwise calibrated to the curl type. |
| All Types (Overnight) | Friction damage, breaking curl clumps during sleep | Mulberry Silk Pillowcase | Applies to every curl type from 2A to 4C. Cotton friction disrupts curl clumps and lifts the cuticle overnight. Silk preserves the wash-day definition into day two for all pattern types. |

"Honestly, I had given up on curl products because nothing was working. My hair always felt coated and heavy. Then I switched to the PCH routine and everything changed. My curls actually absorb the products now and my hair feels clean for the first time in years."
"Every product in this bundle does what it claims. The conditioner makes my hair soft and detangling easy. The curl cream is a perfect balance of moisture and hold. My curls are defined, soft, with less frizz. I love that everything feels nourishing rather than coating my hair."
"Since I switched to this routine, my hair has more body, more definition, and more length than it has had in decades. The products hold through the day, even in British weather, which was never something I could say before. I can see the difference in how much less it breaks when I detangle."
"So many times I thought I had found my holy grail product, only to be disappointed the next day. When I got the amount right with this curl cream, perfect defined curls with bounce that lasted three days. The products hold through the day, even in British weather."
What Is Mixed Curl Type Hair and How Should You Approach It?
Mixed curl type hair is the norm, not the exception. The Zenvy Beauty curl archetype analysis confirms that most people have at least two adjacent pattern types across different zones of the head. The crown often curls tighter than the nape. The front hairline frequently sits one letter looser than the back sections. The underneath layers, which receive less humidity and friction, often hold a tighter pattern than the outer canopy layers.
The practical approach for mixed curl types is to identify the dominant pattern (the one covering the largest area of the head), use that as the primary basis for product selection, and adjust the application method rather than the product for the secondary pattern zones. Looser sections receive less product. Tighter sections receive more. The same product works across adjacent curl types when the application amount is calibrated per zone rather than applied uniformly. The PCH curl quiz accommodates mixed types in its recommendation output by asking about both the primary and secondary patterns you observe.
One pattern combination is particularly common among UK curl owners and worth noting specifically: 2C to 3A. Many people in this range identify as either 2C or 3A, depending on the day, the humidity, and how recently they chelated. The reference object distinction helps: 2C coils are Sharpie-barrel diameter (14 to 18mm), while 3A begins at 10 to 16mm (chalk width). If your curls sit right at the boundary, treat them as 3A for product selection because 3A products provide enough moisture for the borderline pattern without weighing it down, while 2C-focused lightweight products can leave the tighter sections underdefined.
Why Choose The Pure Curls House, Whatever Your Curl Type
Products Across the Full 2A to 4C Spectrum
The PCH range covers every curl type from loose 2A waves to tight 4C coils with products formulated for the specific moisture needs of each pattern. The All-in-1 Curl Cream suits Type 2 and 3 patterns. The Plant Peptide Butter Cream suits Type 3C to 4C. The Ayurvedic oil range supports all types as pre-wash or finishing treatments.
The Chelating Step That UK Curl Type Tests Need First
The Rosemary Root Stimulating Shampoo Bar removes UK hard water mineral deposits that flatten and suppress curl patterns, ensuring that whatever curl type you identify on test day is your actual pattern and not a mineral-masked version of it. No UK curl type guide recommends this step before testing, but it is the most important one for accurate results.
PurePep Peptides That Work Across All Curl Types
The PurePep small-molecule plant peptides in the PCH conditioner and curl cream penetrate the cortex to reinforce protein bonds at the curl bend points, which are the highest-stress locations in any curl type from 3A through 4C. This structural reinforcement is beneficial at every pattern level and improves definition quality regardless of curl type.
UK Climate-Specific Formulation for All Seasons
PCH products are formulated to work across UK seasonal humidity swings, from summer outdoor 80 percent humidity to winter indoor 30 to 40 percent. The Phytocurl film-former in the curl cream does not rely on glycerin as its primary mechanism, which means it performs consistently across all four seasons without the glycerin reversal issues that affect humidity-dependent products in UK winter.
The Curl Quiz Matches Products to Your Specific Type
The PCH Curl Quiz at thepurecurlshouse.com/pages/quiz accounts for pattern type, porosity, density, and seasonal UK conditions in its output. It is updated regularly as new products are added to the range. Retaking it after any significant change (post-partum, post-colour, post-chelating discovery) ensures the recommendation stays current for your actual hair.
75-Day Guarantee Covers the Full Routine Calibration Window
Calibrating products to a newly identified curl type takes 4 to 8 wash days, not just the first wash. The 75-day guarantee covers this full calibration window and several weeks of settled results beyond it, providing the time needed to confirm whether the curl type identification and product match are producing the results expected.
What Makes The Pure Curls House Different for Every UK Curl Type
Most curl care guides identify your type but never address the UK-specific factors that distort the test result or change what products you actually need:
- Chelating before curl type testing: the step that no international quiz includes, but every UK curl owner needs for an accurate result

Frequently Asked Questions About Curl Type in the UK
What is my curl type, and how do I find it?
Your curl type is identified by washing your hair, air drying completely with no products and no touching, and comparing the natural pattern to the 2A to 4C chart. Type 2 (wavy) forms S-bends that do not loop back on themselves. Type 3 (curly) forms defined spiral loops. Type 4 (coily) forms tight Z-pattern or densely packed coils with 50 to 75 percent shrinkage. For UK curl owners specifically, chelate first using a chelating shampoo bar to remove hard water mineral deposits before testing, since mineral buildup can flatten and suppress the true curl pattern, making the test result looser than the actual genetic type. Most people have at least two adjacent pattern types across different head zones, which is completely normal.
What is the difference between curl types 2A, 2B and 2C?
2A is the loosest wavy pattern with very gentle S-bends and a coil diameter of 25 to 30mm, roughly a 2 pence coin width. The pattern is often barely visible and appears almost straight at the roots. 2B is a more defined S-wave that starts from mid-length down, with the roots remaining relatively straight and the coil diameter at 18 to 25mm (a permanent marker barrel). 2C has strong S-waves from the root with occasional loose spirals at the ends, a coil diameter of 14 to 18mm (Sharpie barrel), and is often misidentified as 3A. All three Type 2 patterns are weight-sensitive: products that suit Type 3 curls are usually too heavy for Type 2 waves and flatten rather than define them.
What is the difference between curl types 3A, 3B and 3C?
3A is loose, springy spirals with a coil diameter of 10 to 16mm (sidewalk chalk width) and 20 to 35 percent shrinkage. It is the most common Type 3 subtype. 3B is springy ringlets with a 6 to 10mm coil diameter (pencil width) and 35 to 50 percent shrinkage, typically with high density and significant dryness at mid-lengths and ends. 3C is tight corkscrew curls with a 5 to 8mm coil diameter (drinking straw width) and 45 to 60 percent shrinkage. 3C sits at the border with Type 4, and many people have both 3C and 4A patterns on the same head. All three need weekly deep conditioning, but 3C and 3B require richer products than 3A and benefit from section-by-section application due to the tighter coil density.
Why does UK hard water affect my curl type test?
UK hard water contains calcium and magnesium minerals that deposit on the cuticle surface with every wash. These deposits add weight to each strand and flatten the cuticle surface. The added weight pulls curls downward, stretching coil diameter and suppressing the natural pattern. A Type 3A pattern under significant mineral buildup can appear as a loose 2C wave. A genuine 3B may look like a 3A. This means UK curl owners who test their type without first chelating are frequently identifying the mineral-masked version of their pattern rather than their actual genetic type. Monthly chelating with the Rosemary Root Stimulating Shampoo Bar removes the mineral layer before testing, producing an accurate result.
Is curl type or porosity more important for choosing products?
Both matter, but porosity often affects product results more dramatically than curl type alone. Two people with identical 3B curl patterns can need completely different products if one has low porosity (tightly closed cuticle needing heat during conditioning and lightweight products) and the other has high porosity (open cuticle needing richer products and protein support). Curl type tells you the shape. Porosity tells you how moisture enters and leaves the strand. For UK curl owners, porosity readings can also be distorted by hard water mineral buildup in the same way curl type readings are, so chelating before testing porosity, as well as before testing curl type, produces more accurate results.
Can my curl type change over time?
The genetic curl pattern determined by follicle shape does not change permanently. However, how that pattern expresses itself changes significantly under several conditions. Hormonal shifts during and after pregnancy can tighten or loosen the apparent curl pattern. Chemical treatments (bleaching, colouring, relaxing) permanently alter the disulphide bond network in the processed sections, loosening the pattern in those lengths while new growth retains the original genetic type. UK hard water buildup suppresses and flattens the apparent pattern. Seasonal UK humidity changes make patterns appear tighter in winter and looser in summer. None of these are actual changes to the genetic curl type; they are temporary changes in how the type expresses itself under different conditions.
What products should I use for Type 2 wavy hair UK?
Type 2 wavy hair needs lightweight products that define the wave pattern without weighing it down. The PCH All-in-1 Curl Cream is suitable for all three Type 2 subtypes (2A, 2B, 2C) because the Phytocurl plant film-former provides definition and humidity resistance without the heavy emollient base that flattens Type 2 waves. Use a very small amount (coin-sized for 2A, slightly more for 2C) applied to soaking-wet hair using the scrunching technique rather than praying hands. Do not use the Plant Peptide Butter Cream on Type 2 hair as it is too rich for these patterns and will flatten waves rather than define them. The Cocoa Vanilla Moisturizing Shampoo Bar provides the right level of gentle cleansing without stripping the fine natural oils that Type 2 hair relies on more than heavier curl types.
How do I know if I have Type 2 wavy or Type 3 curly hair?
The defining difference is whether the strand loops back on itself. Type 2 wavy hair bends in an S-shape but does not form a complete loop. Type 3 curly hair forms a defined spiral that loops back toward the starting point. A practical test: take a single dry, product-free strand and hold it up with both ends. If the strand forms a gentle S-bend that does not close into a loop, it is Type 2. If it forms a defined spring or ringlet that loops, it is Type 3. The boundary between 2C and 3A is the most commonly confused. 2C forms tight S-waves, occasionally producing loose spirals at the ends. 3A forms consistent spirals from root to tip. In UK conditions, if the result is unclear after testing, chelate first (to remove mineral-deposit weight that suppresses the pattern) and retest. After chelating, a genuine 3A will show visible spirals; a genuine 2C will still show S-waves even without the mineral weight.
