PCOS Hair Loss Treatment London. Why It Happens And What Works

PCOS-related hair thinning is driven by androgens and, in many women, insulin resistance, which means treating the scalp alone will not fix it. The thinning follows the female pattern, widening at the parting with the hairline preserved, and it responds best when the hormonal and metabolic drivers are addressed alongside direct follicle treatment. That requires blood tests, not a scalp product.

Key points

• Polycystic ovary syndrome affects roughly one in ten women of reproductive age and is a leading cause of androgen-driven hair thinning in women.

• The pattern is diffuse thinning at the crown and a widening parting, with the frontal hairline usually preserved, often alongside unwanted facial or body hair and irregular periods.

• Treating the cause means addressing androgens and insulin resistance, which needs blood tests covering androgens, SHBG, the free androgen index and metabolic markers.

• PRP supports the follicle but does not change the hormonal driver, so it works as part of a plan rather than as the plan.

Why PCOS causes hair thinning

PCOS is a hormonal and metabolic condition characterised by higher androgen activity, irregular ovulation and, in many women, insulin resistance. Androgens are converted in the skin to dihydrotestosterone, and in follicles that are genetically sensitive to it, DHT progressively shrinks the follicle so each growth cycle produces a finer, shorter hair. Over years this reduces density.

The frustrating part is that the same hormones behave differently in different places. On the scalp they thin hair, while on the face and body they can increase it, which is why women with PCOS often deal with unwanted hair growth and scalp thinning at the same time. Insulin resistance compounds it, because higher insulin levels drive the ovaries to produce more androgens and lower sex hormone binding globulin, the protein that keeps testosterone inactive in the bloodstream. Less binding globulin means more free, active androgen reaching the follicle. As our doctors put it, “the scalp is where you see it, but it is not where it starts.”

What the thinning looks like

PCOS-related loss follows the female pattern. The parting widens, the crown thins diffusely, the ponytail feels noticeably thinner, and more scalp becomes visible under bright light or in photographs. The frontal hairline is usually preserved, which distinguishes it from a receding male-pattern hairline and from scarring conditions such as frontal fibrosing alopecia.

Other clues often sit alongside it, including irregular or absent periods, unwanted facial or body hair, acne particularly along the jawline, difficulty losing weight, and skin tags or darker velvety patches at the neck and underarms that suggest insulin resistance. Not every woman with PCOS has all of these, and some have very few, which is part of why the hair thinning is frequently treated as a standalone problem for years before anyone connects it.

The blood tests that actually matter

We publish this in full because it is more useful to you than keeping it back, and because most women with PCOS-related thinning have never had the right panel run.

For the hormonal picture, total testosterone, sex hormone binding globulin and the free androgen index calculated from them, which is more informative than testosterone alone. Alongside these, LH and FSH, oestradiol, DHEAS to check the adrenal contribution, and prolactin to exclude other causes.

For the metabolic picture, HbA1c and fasting glucose, with fasting insulin where indicated, because insulin resistance is a treatable driver of the whole problem.

For the general hair picture, ferritin and iron stores, full thyroid function rather than TSH alone, vitamin D, B12 and zinc, since deficiencies are common in women and independently suppress hair growth.

NICE and the British Association of Dermatologists both stress identifying the underlying cause before treating hair loss. With PCOS that is not a formality, because the results change what you should actually be doing.

What treats the cause

The plan has two halves and both matter. Addressing the driver comes first. Depending on your results and your goals, that may involve improving insulin sensitivity through weight and dietary changes and, where appropriate, medication such as metformin, hormonal treatment such as a combined oral contraceptive to raise binding globulin and lower free androgen, or an anti-androgen such as spironolactone, which is used off-label for this purpose and requires reliable contraception. These are prescribing decisions and need a doctor who has seen your bloods.

Supporting the follicle is the second half. Topical minoxidil is suitable for women and has good evidence, and PRP uses growth factors concentrated from your own blood to stimulate miniaturising follicles, supported by a 2025 meta-analysis in Dermatology and Therapy pooling 43 randomised controlled trials and 1,877 participants finding it increases hair density. Pooled data also show PRP combined with minoxidil outperforms either alone. Correcting any deficiency found on testing sits alongside both.

Where PRP fits, honestly

PRP is useful here and it is not the answer on its own. It acts on the follicle, improving the local environment and stimulating hairs that are miniaturising but still alive. What it does not do is lower your androgens or improve your insulin sensitivity, so if those drivers are left untreated the underlying process continues and results fade faster.

This is why we would rather see your bloods before we discuss treatment at all. A woman whose free androgen index is high and whose HbA1c is creeping up will get a far better and more durable result from a plan that addresses both, with PRP layered on, than from a course of PRP alone. It is also why a clinic that offers PRP without the ability to test and prescribe is poorly placed to manage PCOS-related thinning, however good its injection technique.

Expect results to build over months rather than weeks, and expect the plan to be long term, because PCOS is a long-term condition.

What treatment costs in London

Flagship Harley Street and Mayfair clinics commonly charge £600 to £850 or more per PRP session, and London practices generally charge 50 to 70 percent more than clinics outside the capital. A course of around three sessions with maintenance every six to twelve months is the usual structure.

At The London PRP Clinic by The Wellness, care is doctor-led and priced below those flagship rates, with your plan and the exact figure confirmed after your free suitability review. Blood testing is run from the same clinic rather than referred out, so assessment and treatment sit with one medical team.

The most valuable spend, though, is the diagnosis. A woman treating PCOS-related thinning as a scalp problem can spend years and a great deal of money on products aimed at the wrong level of the problem.

The suitability review

Every enquiry begins with a free doctor-led suitability review rather than a booking. A GMC-registered doctor examines your scalp with dermoscopy, reviews or arranges the blood panel above, and gives you one of two answers.

Approved for treatment, with a clear plan covering both the hormonal or metabolic driver and the follicle, and realistic expectations for three, six and twelve months. Or not approved, in which case we say so and explain what would serve you better, which sometimes means treating the underlying condition first and reviewing your hair in six months, or referring you onward if a different diagnosis is more likely.

We decline a meaningful share of enquiries, and with PCOS that is often because the right first move is not a scalp treatment at all.

Frequently asked questions about PCOS hair loss

Does PCOS cause hair loss?

Yes. Higher androgen activity, often with insulin resistance, shrinks genetically sensitive scalp follicles, producing diffuse thinning at the crown and a widening parting with the hairline usually preserved.

Can PCOS hair loss be reversed?

It can often be slowed, stabilised and partly rebuilt, particularly when caught early and when the hormonal and metabolic drivers are treated alongside the follicle. Follicles that have fully closed do not return.

Which blood tests should I have?

Total testosterone, sex hormone binding globulin and the free androgen index, plus LH, FSH, oestradiol, DHEAS and prolactin, alongside HbA1c and glucose, and ferritin, full thyroid function, vitamin D, B12 and zinc.

Does PRP work for PCOS hair loss?

It helps by stimulating follicles that are still alive, but it does not change androgen levels or insulin resistance, so it works best as part of a plan that also treats the driver.

Why do I have thinning hair on my head and more hair on my face?

Androgens act differently by site, thinning genetically sensitive scalp follicles while stimulating facial and body hair, which is why both can occur together in PCOS.

How long before I see results?

Expect months rather than weeks, with early change from around three months and fuller results over six to twelve, and expect the plan to be long term since PCOS is a long-term condition.
