If you've noticed more hair in the plughole, a parting that seems to widen every month, or a ponytail that feels half the size it used to be, you are not imagining it. And you are very far from alone. Somewhere around half of women experience noticeable hair thinning during the menopausal transition, and yet almost nobody warns us it's coming. We're told about hot flushes. We're told about sleep. Hair barely gets a mention until it's already happening.
The question I hear most often goes something like this: "I've always had thick hair. It doesn't run in my family. My mum still has a full head of it at 72. So why is this happening to me, and why now?"
Here's the honest answer.
It's the hormone shift, not bad luck
Through your twenties and thirties, oestrogen quietly does your hair an enormous favour. It keeps hair in its growing phase, known as the anagen phase, for longer. That's why so many women notice their hair at its thickest and glossiest during pregnancy, when oestrogen peaks, and why hair often sheds dramatically a few months after giving birth when those levels drop again. Oestrogen and hair density are closely linked, and most of us never notice because the arrangement works in our favour for decades.
During perimenopause and menopause, oestrogen and progesterone decline. Two things happen as a result.
First, the growing phase shortens. Hairs spend less time in anagen and move into the shedding phase sooner. More hairs shed at once, and fewer are actively growing at any given moment. Overall density drops even if nothing else changes.
Second, androgens gain the upper hand. This is the part most women are never told. Your testosterone levels don't necessarily rise at menopause. But with far less oestrogen to balance them, their relative influence grows considerably. Some of that testosterone converts into DHT (dihydrotestosterone) via an enzyme called 5-alpha reductase, and DHT is the hormone that gradually shrinks sensitive hair follicles on the scalp.
This is why menopausal thinning tends to show up in such a specific pattern: at the parting, at the temples, across the crown. Those follicles are typically the most DHT-sensitive ones you have. It's also why the front hairline often stays intact, which is precisely why so many women don't realise how much density they've lost until they see a photograph taken from above and get a genuine shock.
Why it happens even with no family history
Genetics influence how sensitive your follicles are to DHT. But here's the thing: the hormonal shift of menopause can be enough to tip the balance on its own, even in women whose sensitivity is relatively mild. Your mother may have sailed through with thick hair into her seventies because her particular combination of follicle sensitivity, hormone levels and timing worked out differently. Yours has landed differently. That isn't a moral failing and it isn't something you caused.
I want to say that clearly, because so many women carry a quiet sense of guilt about this, as though they must have done something wrong. Too much heat. Too many colours. Not enough of some vitamin they read about once. In the overwhelming majority of cases, hormonal thinning at midlife is a hormonal event, not a punishment for your styling habits.
Ruling out the other culprits
Hormones are the most common driver at this life stage, but they're not the only one, and it's genuinely worth ruling out the others before you settle on an explanation. Ask your GP to check:
-
Ferritin (your stored iron). Low ferritin is one of the most common reversible causes of shedding in women, and perimenopause often brings heavier, more erratic periods that drain iron faster.
-
Thyroid function. Both underactive and overactive thyroid cause hair changes, and thyroid problems cluster around midlife.
-
Vitamin D. Deficiency is widespread in the UK and linked to shedding.
-
Full blood count, to check for anaemia.
If your results come back "normal" but sit right at the bottom of the reference range, it's entirely reasonable to ask about that. Normal enough to avoid anaemia is not the same as optimal for hair growth, and the difference matters.
What's actually happening at follicle level
Understanding this next bit changes how you think about the whole problem, so bear with me.
Hormonal thinning works through a process called miniaturisation. Under DHT's influence, and with less oestrogen protecting them, each affected follicle produces a slightly finer, shorter, weaker hair with every growth cycle. The follicle is still alive. It's still working. It's just underperforming, a bit more with each cycle.
This is genuinely good news, because a miniaturising follicle can be supported back towards stronger growth. A follicle that has sat dormant for many years is a much harder proposition. That's the honest boundary line, and it's the single best argument for acting sooner rather than waiting to see how bad things get.
What actually helps
Because DHT is a central part of the picture, ingredients studied for their effect on DHT are a logical place to start.
-
Saw palmetto. A plant extract studied for its ability to inhibit 5-alpha reductase, the enzyme that creates DHT. Research shows it can help reduce DHT levels by up to 30%.
-
Pumpkin seed oil. In a 2014 randomised, placebo-controlled study (Cho et al.), participants taking 400mg of pumpkin seed oil daily saw a 40% increase in mean hair count over 24 weeks, compared with 10% in the placebo group.
These are the two ingredients behind our Hair Growth Softgels, at the doses used in the research: 400mg pumpkin seed oil and 300mg saw palmetto. Not a sprinkle for the label. The amounts the studies actually used.
They are not an overnight fix, and they're not a replacement for medical treatment where that's needed. If your GP or dermatologist recommends a licensed treatment, that's a perfectly sound route and worth taking seriously. But taken consistently, research-backed ingredients support your hair from the inside by addressing the hormonal mechanism, rather than sitting on the surface making things temporarily look thicker.
Alongside the inside work
Be kind to the hair you have while the rest catches up. Looser styles rather than tight ponytails, since constant tension pulls at exactly the areas already under strain. Less heat, always with a protectant. Gentle detangling from the ends upwards. A silk or satin pillowcase to reduce overnight friction. None of these will regrow hair, but they'll stop you losing length and volume to breakage while your follicles are doing the slow work.
The one thing that determines your outcome
Consistency, and starting early. Follicles that have recently begun to shrink respond far better than follicles that have been dormant for years. Hair works in months, not weeks: shedding typically slows first, within the first few weeks, then texture and strength improve across months one to three, and new growth usually appears around month three and builds from there.
The women who see real change are almost always the ones still going at month six, not the ones who gave up at week five because the mirror hadn't changed yet. That middle stretch, where shedding has calmed but nothing visible has arrived, is where most people quit. It's also precisely when the work is happening, just under the skin where you can't see it. If you take one thing from this article, make it that.
