HRT can be one of the best things you do for your hair — or the quiet reason it is thinning. The difference usually comes down to which preparation you are on, because oestrogen generally supports hair while some progestogens work against it. If your hair changed after starting, switching or stopping HRT, that is worth a proper medical look, not guesswork.
The HRT & Hair Review is a dedicated appointment with Dr Amy Vowler, a GMC-registered doctor: your full HRT history, a magnified scalp examination, the blood tests that matter (if needed) , and a clear answer on whether your current HRT is helping your hair, hindering it, or irrelevant to it — with changes prescribed where appropriate, or agreed with your GP.
- – Oestrogen generally supports hair growth; some progestogens are androgenic and can work against it
- – If your hair changed after starting or switching HRT, the specific preparation may be the reason
- – The review covers your HRT, your scalp under magnification, and bloods that rule out compounding causes
- – We adjust or prescribe where appropriate, or write to your GP — HRT is never prescribed for hair alone
- – Surgical menopause and testosterone-containing regimens need particular care where hair is concerned
Why HRT and your hair are tangled together
Scalp follicles respond to the balance between oestrogens and androgens. Oestrogen holds hairs in their growing phase for longer, which is why many women notice fuller hair in pregnancy and shedding as oestrogen falls at menopause. Well-chosen HRT restores some of that support. But HRT is not one thing: every regimen pairs an oestrogen with a progestogen (unless you have had a hysterectomy), and progestogens differ enormously in how androgenic they are.
That is why one woman’s HRT leaves her hair thicker while another’s coincides with new thinning at the parting. Timing is the clue we look for: changes that begin within months of starting, switching or stopping a preparation point to the hormones; changes that drift in gradually usually point to underlying pattern hair loss that the HRT is simply not addressing.
Hair-friendly and hair-risky: not all HRT is equal
| HRT component | Effect on hair, in general |
|---|---|
| Oestrogen (patch, gel, spray or tablet) | Supportive — the part of HRT most likely to help hair |
| Micronised progesterone (body-identical) | Broadly neutral — the progestogen least likely to trouble hair |
| Older synthetic progestogens (e.g. norethisterone, levonorgestrel) | More androgenic — can aggravate thinning in susceptible women |
| Anti-androgenic progestogens (e.g. drospirenone) | Can actively favour hair in androgen-sensitive women |
| Testosterone (sometimes added for libido and energy) | Helpful for symptoms, but dose and monitoring matter — excess can drive thinning |
General patterns, not rules — individual response varies, and that is precisely what the review is for. We confirm what suits you against your history, your scalp findings and your bloods.

What the review involves
Fifty minutes with the doctor. We map your full hormonal history — every HRT preparation and when your hair changed relative to each — then examine your scalp under magnification to establish what kind of hair loss is actually present. Bloods are arranged where they change the answer: ferritin, thyroid function, and androgens where relevant. You leave with a written plan: whether your HRT should stay, be adjusted or be switched, and what hair-directed treatment to run alongside it.
Where a change is appropriate, Dr Amy can prescribe it directly or write to your GP with the specific recommendation — whichever suits how your HRT is currently managed. One honest limit, stated plainly: we do not prescribe HRT for hair alone. It is a menopause treatment first, and the evidence for hair as a sole indication does not justify it.
Surgical menopause, early menopause and testosterone
Women whose menopause arrived abruptly — after oophorectomy, hysterectomy or early ovarian insufficiency — often experience a harder hormonal landing, and their hair shows it. The review gives this group particular attention, because getting replacement right matters more when there was no gradual transition. The same applies to testosterone: genuinely useful for some menopausal symptoms, but it needs sensible dosing and monitoring in any woman with androgen-sensitive follicles. If you are on it and thinning, we will look at that honestly rather than reflexively.
What Patients Say
Not on HRT yet?
If you are considering HRT for menopausal symptoms and want to start on the most hair-friendly footing, the same review works in advance — we assess your hair, flag which preparations would suit it, and coordinate with whoever will prescribe. For the wider picture of menopause and hair, our menopause hair loss clinic covers the full assessment, and our guide to HRT and hair loss explains the evidence in depth.
Three moments to book the review — and what each one gets
Women arrive at this appointment from three directions. Before starting HRT: you want the menopause benefits without gambling your hair, so we assess your follicles’ androgen sensitivity first and recommend preparations accordingly — hair-friendliness designed in, not retrofitted. After starting or switching: your hair changed and you want to know whether the regimen is the reason — we map the timeline against the preparation, examine what kind of loss is actually present, and adjust or exonerate the HRT with evidence rather than guesswork. Or mid-frustration: you have cycled through combinations, your prescriber keeps saying the HRT is fine, and your parting disagrees — this is where the fifty minutes earns its keep, because “the HRT is fine” and “your hair needs treatment the HRT was never going to provide” are usually both true, and distinguishing them changes everything.
What we check beyond the HRT itself
The menopausal years are crowded with co-conspirators, and blaming the HRT for all of them is the commonest mistake in this clinic’s caseload. Ferritin runs low after decades of periods and rarely gets rechecked once they stop. Thyroid disease peaks in exactly this age band and mimics every hormonal symptom on the list. And female pattern hair loss — which menopause unmasks rather than causes — continues regardless of how elegant the HRT regimen is, and needs its own treatment. The review therefore runs wider than the prescription: scalp examination under magnification to type the loss, bloods where they change the answer, and a plan that treats what is actually driving your hair — with your HRT optimised as one instrument in it, not mistaken for the whole orchestra.

It can, though it more often helps. The usual culprit is the progestogen component: older synthetic progestogens such as norethisterone or levonorgestrel are mildly androgenic and can aggravate thinning in susceptible women. If your hair changed within months of starting or switching a preparation, the regimen deserves a proper review.
As a general pattern: transdermal oestrogen with micronised progesterone is the combination least likely to trouble hair, and anti-androgenic progestogens can actively favour it. But the right HRT depends on your symptoms, history and risk profile — hair is one factor among several, which is why this is a doctor’s review rather than a swap you make yourself.
At sensible doses with monitoring, usually not — but in women with androgen-sensitive follicles, excess testosterone can drive thinning at the crown and parting. If you are using testosterone and noticing hair change, levels are worth checking rather than guessing. We include this in the review where relevant.
Dr Amy is a GMC-registered doctor and can prescribe or adjust HRT where clinically appropriate. She also has undertaken additional training and has completed the British Menopause Society Course so is a menopause specialist as well. Where your HRT is managed by your GP or a menopause clinic, we write to them with the specific recommendation instead — whichever route keeps your care joined up.
Sometimes it helps visibly; often it does not, because underlying pattern hair loss needs its own treatment. The evidence is genuinely mixed, and we will not prescribe HRT for hair alone. What the review does is make sure your HRT is at least working with your hair, then add hair-directed treatment where it is needed.
Withdrawing oestrogen support can trigger a shed, and it can also unmask pattern hair loss that the HRT had been quietly holding back. Either way the hair deserves assessment in its own right, because the effective treatments from here are usually hair-directed rather than a return to HRT for its own sake.
Yes, routinely. You get a written summary of findings and recommendations, and with your consent we write to your GP so any HRT change is made with full information. The aim is one joined-up plan, not parallel prescribing.
