Does PRP Work for Hair Loss in Women. Female Pattern Hair Loss, the Evidence and What Comes First
Yes, for female pattern hair loss with miniaturised follicles. A 2024 meta-analysis of 21 randomised trials found PRP increased hair density and thickness in women with a favourable safety profile. It comes after a blood panel and minoxidil, not instead of them, and it does not treat the shedding, thyroid or iron problems behind much of women's hair loss.
Key points
A 2024 systematic review and meta-analysis of 21 randomised controlled trials, searching to May 2024, found PRP effectively increased hair density and thickness in women with hair loss, with a favourable safety profile, and that effects varied with dosage, injection schedule and ethnicity.
A 2025 meta-analysis in Dermatology and Therapy of 43 randomised trials and 1,877 participants of both sexes found activated PRP increased density and reduced recurrence against placebo, with PRP combined with minoxidil outperforming either alone.
A 2023 pilot open randomised trial compared topical minoxidil alone with minoxidil plus PRP specifically in women with female pattern hair loss, and a 2023 randomised pilot of 30 women with chronic telogen effluvium found PRP better than saline at 3 months.
Finasteride is not licensed for women of childbearing age, which leaves minoxidil as the only licensed first-line treatment and makes PRP a more important addition for women than for men.

Why hair loss in women is a different problem
Men mostly have one kind of hair loss, and it follows a pattern anyone can recognise. Women have several, they overlap, and they look alike from the outside. Female pattern hair loss is the hormone-sensitive miniaturisation of follicles, usually across the crown with a widening parting and a preserved hairline, staged on the Ludwig scale. Telogen effluvium is diffuse shedding after a trigger such as childbirth, illness, weight loss or stress, and it resolves on its own. Iron deficiency, thyroid disease, polycystic ovary syndrome and the menopause each cause or worsen shedding and thinning, and each has its own treatment.
The consequence is that a woman who walks into a clinic with thinning hair may have 1 problem or 3, and PRP only treats 1 of them. It stimulates miniaturised follicles in pattern loss. It does not correct a ferritin of 10, an underactive thyroid or a postpartum shed. A clinic that offers PRP to a woman without a blood panel and a dermatoscope examination is treating the follicle before it knows what is wrong with it, and for a large share of women that is the wrong treatment sold confidently.
What the evidence shows for women specifically
Most PRP hair trials enrolled men, women or both, and the 2025 meta-analysis in Dermatology and Therapy pooled 43 trials and 1,877 participants across both sexes. The 2024 meta-analysis that matters here looked only at women. It searched 6 databases to May 2024, identified 21 randomised controlled trials of PRP for various forms of female hair loss, assessed them with the Cochrane risk of bias tool, and found PRP effectively increased hair density and thickness with a favourable safety profile. It also found the size of the effect varied with dose, injection schedule and ethnicity, which the authors read as a need for tailored protocols rather than a fixed package.
Two smaller trials fill in the picture. A 2023 pilot open randomised trial compared topical minoxidil alone with minoxidil plus PRP in women with female pattern hair loss, testing the combination the larger meta-analysis recommends. And a 2023 randomised, double-blind pilot in the Indian Journal of Dermatology, Venereology and Leprology gave 30 women with chronic telogen effluvium 4 monthly sessions of PRP or saline and found PRP ahead on pull test, density and satisfaction at 3 months. That is the one randomised signal for PRP in shedding, and it is small.

What comes before PRP for a woman
The order is fixed by the evidence and it starts with blood. Ferritin, the iron store, is the commonest correctable cause of thinning in women and the level a follicle needs is higher than the level that defines anaemia, so a normal full blood count does not exclude it. Thyroid function, vitamin D, zinc, B12 and, where the history suggests it, androgen and hormone levels complete the panel. A woman with acne, irregular periods and thinning at the crown has a hormonal picture that a doctor needs to see before any scalp treatment, and a woman at the menopause has a hormone shift that may be part of the cause.
Minoxidil is the licensed first-line treatment for female pattern hair loss and the foundation on which PRP works. Finasteride is not licensed for women of childbearing age because of the risk to a male fetus, and while it and spironolactone are sometimes used off licence in postmenopausal women, that is a specialist decision. The practical effect is that women have fewer licensed tools than men, which is why PRP, as the addition with the most evidence beyond minoxidil, earns a larger place in a woman's plan than in a man's.
Where PRP fits, and where it does not
PRP fits the woman with confirmed female pattern hair loss at Ludwig stage 1 or 2, whose blood panel is normal or corrected, who is on minoxidil, and who wants more density than minoxidil alone has given. It fits the woman who cannot tolerate minoxidil. It fits the perimenopausal or postmenopausal woman whose pattern loss has accelerated and whose options are otherwise limited. In each of those the follicles are miniaturising rather than absent, and that is what the trials treated.
It does not fit the woman 3 months after childbirth, illness or rapid weight loss whose shedding is diffuse and will recover. It does not fit the woman whose ferritin has not yet been checked or corrected. It does not fit a Ludwig stage 3 scalp where the crown is bare, which is a transplant conversation, or a scarring alopecia such as frontal fibrosing alopecia, which needs a dermatologist and where PRP evidence is case reports. A doctor with a dermatoscope can distinguish these in a minute, and the honest sequence follows the diagnosis rather than the menu.
A self-check for women before any hair treatment
Work through this before booking anything, including here.
Where is the thinning. A widening parting and thinner crown with a preserved hairline fits pattern loss. Loss everywhere at once fits shedding. A receding, band-like hairline with lost eyebrows needs a dermatologist urgently, since that fits a scarring alopecia.
What happened 2 to 4 months ago. Childbirth, illness, a new contraceptive, a crash diet or a weight loss injection points to shedding that will recover.
Have you had ferritin, thyroid function, vitamin D, zinc and B12 checked in the last year. If not, that is the first appointment.
Do you have acne, irregular periods, excess facial hair or a diagnosis of polycystic ovary syndrome. That is a hormonal picture a doctor needs to see.
Are you on minoxidil, and have you given it 6 months. It is the foundation and it takes that long.
Are the thinning areas still carrying fine, short hairs. If so, follicles are alive and PRP has a target. Bare skin does not.
Has anyone offered you PRP without asking any of the above.
Our doctors put it this way. A woman's hair loss is a diagnosis before it is a treatment. Half the women who come to us for PRP leave with a blood form and a bottle of minoxidil, and that is the right outcome, not a missed sale.
Message us on WhatsApp with when it started, what else has changed, and photographs, and a doctor will give you a straight answer.
What PRP does not do for women
PRP does not correct iron deficiency, thyroid disease or a hormonal cause, and none of those is improved by injecting the scalp. It does not shorten postpartum or post-illness shedding, which recovers on its own. It does not regrow a crown that has become bare, and it has only case reports in scarring alopecias. Its evidence in women, 21 randomised trials, is consistent in direction but varies with protocol, and the largest meta-analysis rates the wider PRP evidence low quality. It is a course with maintenance, works best on top of minoxidil, and is not available on the NHS.
What it costs, and what a missed diagnosis costs
Flagship Harley Street and Mayfair clinics commonly charge £600 to £850 or more per session of hair PRP, with a course of 3 taking a plan past £2,000 and maintenance on top. A hair loss blood panel costs a fraction of one session and is available privately through The Online GP by The Wellness and elsewhere.
The reframing is the woman with a ferritin of 10. She can spend £2,000 on PRP and watch it fail, or she can spend a fraction of that on the blood test that finds the cause, correct it over 3 months, and then decide whether PRP is needed at all. The most expensive PRP course is the one sold to a scalp that needed iron.
Care at The London PRP Clinic by The Wellness is doctor-led and priced below flagship rates, with your exact figure confirmed at the free suitability review, which for women starts with the cause before the treatment.
Ask about the cost for your hair on WhatsApp and we will explain what the review covers.
The free suitability review
Every enquiry here starts with a free, doctor-led suitability review rather than a booking. A GMC-registered doctor takes a history that covers hormones, pregnancies, medication and triggers, examines the scalp with a dermatoscope, arranges the blood panel, prescribes or reviews minoxidil, and gives one of two answers. Either you are approved for PRP on that foundation, with a clear plan and realistic expectations, or you are not approved yet, with an honest explanation of what to correct first and when to reassess.
We decline a meaningful share of the people who enquire. For women that share is high, because so much of women's hair loss has a cause PRP does not treat.

Frequently asked questions
Does PRP work for female hair loss
Yes, for female pattern hair loss with miniaturised follicles. A 2024 meta-analysis of 21 randomised trials found PRP increased hair density and thickness in women with a favourable safety profile, with results varying by dose and protocol. It does not treat shedding, iron deficiency or thyroid causes.
What blood tests should a woman have before PRP for hair loss
Ferritin, thyroid function, vitamin D, zinc and B12 as a minimum, with androgen and hormone levels where there is acne, irregular periods or a suspicion of polycystic ovary syndrome. A low ferritin is the commonest correctable cause of thinning in women, and correcting it comes before any scalp treatment.
Can women use finasteride for hair loss
Not if they could become pregnant, because of the risk to a male fetus, and it is not licensed for women in the UK. It and spironolactone are sometimes used off licence after the menopause under specialist supervision. Minoxidil is the licensed first-line treatment for women.
Is PRP good for hair loss after menopause
It can be, for the pattern loss that often accelerates at menopause, on top of minoxidil and once thyroid and iron have been checked. Women at menopause have fewer licensed options than men, which makes PRP a more useful addition for them than for men.
Does PRP help postpartum hair loss
No. Postpartum shedding is telogen effluvium, which begins 2 to 4 months after birth and recovers on its own within 6 to 12 months. A 30-patient pilot found PRP helped chronic shedding, but a normal postpartum shed needs time and a ferritin check, not injections.
How many PRP sessions do women need
Most trials used 3 sessions about a month apart, then maintenance every 3 to 6 months, and the 2024 meta-analysis found the effect varied with dose and schedule. A doctor should set the number after examining the scalp, and a single session is a demonstration rather than a treatment.
