PCOS hair loss happens because polycystic ovary syndrome raises androgen (male hormone) levels, and androgens gradually shrink sensitive scalp hair follicles, so hair thins on the head even while unwanted hair may increase elsewhere. It is one of the most frustrating symptoms of PCOS, but it is manageable: the biggest lever is treating the hormonal imbalance itself with your GP or a specialist, while a kind, supportive hair routine protects and flatters the hair you have. Here is the full picture.

What is PCOS?

Polycystic ovary syndrome is a common hormonal condition affecting how the ovaries work, thought to affect around 1 in 10 women, with many undiagnosed. Its three key features are irregular ovulation, higher levels of androgens, and polycystic ovaries on ultrasound. Common symptoms include:

• Irregular periods or none at all
• Excess facial or body hair (hirsutism), from the higher androgens
• Weight gain and difficulty losing weight
• Oily skin or acne
• Thinning hair on the scalp

Why does PCOS cause hair loss?

It is the androgens. Scalp hair follicles, particularly around the crown, parting and temples, are sensitive to androgens, which gradually miniaturise them: each new hair grows finer and shorter until density visibly drops. This is the same mechanism as pattern hair loss, which is why PCOS thinning tends to look like a widening parting and thinner crown rather than patches, and why the same hormones can thin scalp hair while increasing facial and body hair. PCOS hair can also become drier, limper and more prone to breakage.

How to manage PCOS hair loss

1. Start with the hormones (the real fix)

Because the cause is hormonal, the most effective treatments are medical. Your GP, gynaecologist or endocrinologist can investigate and discuss options, which may include hormonal therapy (such as the combined pill) or anti-androgen approaches, alongside managing insulin resistance through diet, exercise and sometimes medication. Weight management, where relevant, can itself lower androgen levels. Hair regrowth follows hormone improvement slowly, think months, so start the conversation early.

2. Support your hair with a gentle routine

While the medical side works, a kind routine keeps hair looking its best:

Grow Me® Hair Growth Shampoo

A sulphate-free shampoo with biotin, caffeine, rosemary, niacinamide and argan oil. It keeps the scalp moisturised and comfortable and supports the look of fuller, stronger-feeling hair, cosmetic support alongside your medical care, not a treatment for PCOS.

Shop Grow Me Shampoo

A nightly scalp massage with the leave-in Grow More elixir keeps the scalp cared-for, and gentle styling, loose styles, low heat, careful detangling, protects fragile strands from breakage.

3. Nutrition, with a PCOS note

Balanced blood sugar and good nutrition are core PCOS management, and hair benefits too: prioritise protein, iron, zinc and B vitamins. A supplement like our GrowPro gummies (biotin and zinc contribute to the maintenance of normal hair) can top things up, but check with your GP or pharmacist first if you take PCOS medication, and ask about testing for iron or vitamin D, which are commonly low.

4. Styling that flatters

• A shorter cut or layers make thinning less visible and add body.
• Volumising, lightweight products lift the roots.
• For coverage days, hair building fibres disguise a widening parting in seconds.

Frequently asked questions

Can PCOS hair loss be reversed?

Often it can improve substantially once androgen levels are brought down with medical treatment, though regrowth is gradual over months.

What does PCOS hair loss look like?

Gradual thinning at the crown, parting and temples, like pattern thinning, rather than patches or sudden shedding.

What is the best treatment for PCOS hair loss?

Treating the hormonal imbalance itself, via your GP or a specialist, is the most effective step. Hair care supports appearance alongside.

Does PCOS hair loss mean I will go bald?

No, PCOS thinning is usually diffuse and manageable, and it responds to treating the underlying hormones.

Which vitamins help with PCOS hair loss?

Biotin and zinc support normal hair, and iron and vitamin D are worth testing as they are commonly low. Check with your GP before starting supplements.

Why does PCOS thin scalp hair but increase facial hair?

Scalp follicles shrink under androgens while facial and body follicles are stimulated by them, the same hormone, opposite effects on different follicles.

PCOS hair loss is hormonal, which means it is treatable at the source: bring your GP or specialist in early, give the medical side time, and support your hair kindly along the way.
