PCOS Hair Loss: Why It Happens and How to Manage It Naturally
Zara Inuwa
PCOS hair loss is caused by elevated androgens shrinking hair follicles and shortening the active growth phase. It typically shows as diffuse thinning across the scalp rather than patches. Managing it requires both internal support (diet, nutrition, speaking to your doctor) and external care (scalp stimulation, the right products). No topical product cures PCOS, but consistent scalp care and the right routine can significantly improve hair quality and reduce additional shedding caused by dryness and breakage.
Polycystic Ovary Syndrome (PCOS) is a common hormonal condition that affects how the ovaries work. Many women in the UK are diagnosed with PCOS. Some experience no symptoms at all, while others deal with a range of effects including irregular periods, skin changes, and PCOS hair loss. When PCOS affects hair, it typically causes the hair on the scalp to thin gradually, a condition known as androgenic alopecia or female pattern hair loss.
If you have been noticing more hair in your shower drain or on your hair tie and suspect PCOS may be a factor, this guide explains exactly what is happening, what truly helps, and how to build a care routine that supports your hair through it.
Why PCOS Causes Hair Loss
PCOS causes the body to produce excess androgens, which are hormones typically associated with male characteristics. In women with PCOS, elevated androgen levels create a hormonal imbalance that affects hair follicles directly. Androgens, particularly DHT (dihydrotestosterone), bind to receptors in the hair follicles and gradually miniaturise them. A miniaturised follicle produces a thinner, shorter strand and eventually enters the resting and shedding phase sooner than it should.
The result is diffuse thinning across the scalp rather than a defined bald patch. Hair typically becomes finer at the crown and temples first, while the overall density decreases gradually. This is different from the patchy hair loss caused by alopecia areata, and it tends to progress slowly rather than appearing suddenly.
It is important to understand that PCOS hair loss happens at the follicle level, which is why topical products alone cannot reverse it. Managing the hormonal component, usually with the help of your doctor, is the most fundamental step. Everything covered below addresses how to support your hair and scalp while managing PCOS, not replace medical care.
Other Factors That Can Worsen Hair Loss Alongside PCOS
PCOS is often not the only factor affecting hair when shedding is excessive. Several conditions commonly occur alongside PCOS and can compound hair thinning significantly:
Iron deficiency anaemia: Low iron is one of the most common causes of hair shedding in women, and it is particularly common in women with PCOS who experience heavy periods. When the body is low in iron, it prioritises iron for vital organs over hair follicle function. A simple blood test ordered by your GP can confirm whether iron levels are contributing to your shedding.
Vitamin D deficiency: Vitamin D receptors are found in hair follicles, and low levels are consistently associated with hair thinning. UK winters and limited sun exposure make vitamin D deficiency very common in Britain regardless of skin tone.
Zinc deficiency: Zinc is involved in the protein synthesis that produces each hair strand. Deficiency slows growth and increases shedding. Zinc levels can be assessed alongside iron and vitamin D via a blood test.
Chronic stress: Prolonged stress triggers a form of diffuse shedding called telogen effluvium, where a large proportion of follicles enter the resting phase simultaneously. This can occur weeks to months after a stressful period and temporarily increases shedding significantly.
Thyroid conditions: Both hypothyroidism and hyperthyroidism can cause hair thinning and are more common in women with PCOS. A thyroid panel is worth requesting if your hair loss is severe or accompanied by fatigue, weight changes, or temperature sensitivity.
It is normal to shed approximately 50 to 100 hairs per day. If you have Type 3 or Type 4 curly or coily hair, you may notice more hair on wash day because shed hairs tangle within your curl pattern between wash days and release all at once when you cleanse and detangle. This can look alarming but may reflect several days of normal shedding rather than an acute increase.
If you are concerned about your shedding level, speak with your GP. A blood test covering iron, ferritin, vitamin D, zinc, B12, and thyroid function gives a clear picture of any nutritional or hormonal factors contributing to your hair loss.
How to Manage PCOS Hair Loss: Inside and Outside
Internal Support: Diet, Nutrition, and Medical Treatment
Because PCOS hair loss originates from a hormonal and nutritional environment, the most impactful changes start from within. Topical products can improve hair quality and reduce additional breakage, but they work best as part of a complete approach that also addresses internal factors.
Protein: Hair is made primarily from keratin protein. A diet low in protein directly slows hair growth and weakens each strand. Include eggs, legumes, fish, lean meat, and plant proteins at each meal.
Iron-rich foods: Leafy greens, lentils, red meat, and fortified cereals support iron levels. Pair plant-based iron sources with vitamin C to improve absorption.
Healthy fats: Omega-3 fatty acids found in oily fish, walnuts, and flaxseed support follicle health and reduce the inflammation that can worsen hormonal hair thinning.
Low glycaemic eating: PCOS is often associated with insulin resistance, and high blood sugar spikes can worsen androgen production. A diet lower in refined carbohydrates and higher in fibre helps manage insulin levels and can reduce androgen-related effects on hair.
The hair growth supplements guide covers which vitamins and minerals matter most for hair health and how to identify whether a deficiency may be affecting your growth. Internal supplementation alongside a good diet can make a meaningful difference when hair loss has a nutritional component.
Medical options: If hair loss is significant, speak with your GP about options including hormonal management of PCOS, anti-androgen treatments, or referral to a dermatologist. PCH does not provide medical advice, and the products below are not a medical treatment for PCOS.
External Support: Scalp Care and the Right Products
While topical products cannot alter the hormonal cause of PCOS hair loss, they play a real role in supporting the scalp environment and minimising the additional hair loss caused by poor scalp health, dryness, breakage, and inadequate follicle circulation. This is where The Pure Curls House product range makes a real difference.
PCH Products That Support Hair With PCOS
Rosemary Ayurvedic Oil: Scalp Stimulation and Follicle Support
Rosemary has one of the strongest documented records of any botanical ingredient for scalp health and hair growth support. The PCH Rosemary Ayurvedic Oil is formulated around rosemary as the lead ingredient, supporting scalp circulation and follicle activity when applied with consistent massage. For PCOS-related hair thinning, where follicle circulation is already compromised by hormonal factors, regular scalp massage with a stimulating oil addresses circulation from the outside while other interventions address the hormonal causes internally.
Apply two to three times per week to the scalp, massage firmly for four to five minutes using the pads of your fingers or the PCH Scalp Massager, and leave in or cover with a shower cap before washing. Consistency over months produces the most noticeable results. The scalp oil for hair growth guide covers the full application technique and what to expect from each stage of consistent use.

PCH Scalp Oil: Nourishing Dry, Irritated Scalp
Hormonal fluctuations associated with PCOS can increase scalp sensitivity, dryness, and in some cases dandruff. The PCH Scalp Oil contains 12 natural ingredients including black seed oil, castor oil, lavender, and rosemary specifically formulated to relieve dry, irritated scalp conditions. A healthier, less inflamed scalp provides a better environment for follicle function, and addressing scalp health is a foundational step in any hair loss management routine. For a complete guide to scalp care, the scalp health for curly hair UK guide covers all major scalp conditions and how to address them.

Superfood Hair and Scalp Elixir: Internal Nutritional Support
The Superfood Hair and Scalp Elixir provides internal nutritional support with vitamins and minerals formulated to support hair health from within. For women with PCOS managing nutritional deficiencies that compound hair thinning, internal supplementation alongside dietary improvements gives the follicles a better nutritional environment to work in. This product is not a medical treatment for PCOS, but it addresses the nutritional side of hair health that topical products cannot reach.

Mint and Cocoa Ayurvedic Butter Treatment: Reducing Breakage
PCOS hair is often both thinning at the follicle level and breaking at the strand level. Thinner, finer strands produced by miniaturised follicles are more fragile and need more careful conditioning to stay intact. The Mint and Cocoa Ayurvedic Butter Treatment used as a weekly or fortnightly deep conditioning mask reduces the breakage at the ends that compounds thinning caused by PCOS. It contains fenugreek seeds which strengthen the hair shaft and reduce shedding, alongside cocoa butter for intensive moisture and cuticle repair. Reducing breakage while supporting growth gives the hair its best chance of visible improvement.
Protein and Moisture Balance for PCOS Hair
PCOS-related thinning produces finer strands that are structurally weaker than pre-PCOS hair. These finer strands are more prone to both moisture loss and protein depletion, which means the right treatment balance matters more than for healthy, dense hair.
Moisture first: If hair feels dry, brittle, or rough, prioritise deep conditioning. Apply the Mint Cocoa Ayurvedic Butter Treatment weekly as a pre-wash mask. Moisture deficiency is the most common cause of additional breakage in PCOS hair.
Protein monthly: The PCH Plant Peptide Conditioner used as an extended 15 to 20 minute treatment once a month provides a gentle protein boost that reinforces finer strands without causing protein overload. Avoid heavy or frequent protein treatments on already fragile PCOS hair, as protein overload makes brittle strands worse.
Gentle handling: Reduce mechanical stress on thinning hair. Detangle with a wide-tooth comb on saturated, conditioned hair only. Avoid tight styles that apply tension at the hairline. Sleep on a silk or satin surface to reduce overnight friction. The protein treatment guide explains how to identify whether your hair needs protein or moisture and how to get the balance right for finer, more fragile strands.

Frequently Asked Questions: PCOS and Hair Loss
Frequently Asked Questions
Does PCOS always cause hair loss?
Not always. Many women with PCOS do not experience noticeable hair loss. Whether PCOS causes hair thinning depends on the degree of androgen excess, individual follicle sensitivity to androgens, and other factors such as iron levels, stress, and nutrition. Some women with PCOS only notice increased shedding during hormonal fluctuations such as stopping the pill or during periods of significant stress.
Can PCOS hair loss be reversed?
In many cases, yes, at least partially. If the hormonal component of PCOS is managed, androgenic miniaturisation of the follicle can slow or stop. Follicles that have been miniaturised but not permanently damaged may recover when androgen levels normalise. Nutritional deficiencies contributing to hair loss, such as iron or vitamin D deficiency, can be corrected and their hair effects reversed. Speak to your GP or a dermatologist about the options available to you.
How do I know if my hair loss is from PCOS or something else?
PCOS hair loss typically presents as diffuse thinning across the scalp, particularly at the crown and temples, with strands becoming progressively finer rather than falling out in patches. A blood test checking iron, ferritin, vitamin D, zinc, B12, and thyroid function helps rule out nutritional deficiencies and thyroid conditions that cause similar symptoms. Your GP can arrange this test and refer you for further investigation if needed.
Can scalp massage help PCOS hair loss?
Scalp massage stimulates blood circulation to the follicle bed, delivering more nutrients and oxygen to follicles that may already be compromised by androgen sensitivity. While massage cannot reverse the hormonal cause of PCOS hair loss, consistent scalp massage two to three times per week alongside a stimulating oil like the PCH Rosemary Ayurvedic Oil supports the best possible follicle environment from the outside.
What vitamins help with PCOS hair loss?
Iron, ferritin, vitamin D, zinc, and B vitamins including biotin are the nutrients most commonly linked to hair thinning when deficient. Women with PCOS are particularly prone to iron deficiency if they experience heavy periods, and vitamin D deficiency is widespread in the UK. A blood test via your GP can identify specific deficiencies. Supplementing what you are truly deficient in, rather than taking everything, is the most effective approach.
Does diet affect PCOS hair loss?
Yes, significantly. A diet high in refined carbohydrates can worsen insulin resistance, which in turn worsens androgen production in PCOS. A lower glycaemic diet rich in protein, healthy fats, and fibre helps manage insulin levels and can reduce androgen-related hair effects over time. Adequate protein intake also ensures follicles have the building blocks to produce strong strands.
PCOS hair loss is real, it is common, and it is manageable. The most effective approach combines medical support for the hormonal component with nutritional improvements and a consistent external care routine that supports the scalp and reduces the additional breakage that compounds thinning. The Pure Curls House products are not a cure for PCOS, but they are formulated to help women managing this condition give their scalp and strands the best possible environment to thrive. Explore the full Growth and Repair collection, read the how to grow curly hair longer UK guide for a complete growth-focused routine, or take the curl quiz for a personalised recommendation. If you feel your hair is shedding in excess, speak with your doctor, who can arrange a blood test to identify or rule out any underlying causes.
