Female Pattern Hair Loss After Menopause: Why Is My Hair Thinning?

If you have recently been told that you have androgenetic alopecia, you may be wondering what that actually means.

Does it mean you have too much testosterone?

Has menopause caused your hair loss?

Should you ask your GP to check your hormones?

A 2026 review by Anderson, Rudnicka and colleagues looked specifically at the relationship between female androgenetic alopecia and menopause. Its message is clear: female pattern hair loss becomes much more common after menopause, but it is not simply a problem of high testosterone.

What is female androgenetic alopecia?

Female androgenetic alopecia, also called female pattern hair loss, is a non-scarring form of hair loss.

The follicles are not destroyed. Instead, some gradually become smaller — a process called miniaturisation.

A follicle that once produced a thick, long hair starts producing a finer, shorter one. As more follicles are affected, overall density reduces and more scalp may become visible. This usually develops gradually.

On trichoscopy, we can look for signs such as variation in hair thickness and increasing numbers of finer hairs.

Why does it become more common after menopause?

Female pattern hair loss can occur before menopause, but it becomes much more common with age.

The review cites estimates of around 17% of premenopausal women and 53% of postmenopausal women being affected, although prevalence varies between populations.

The obvious question is: why?

The answer appears to be the changing hormonal environment around menopause.

Estradiol falls markedly as ovarian function declines. Progesterone also falls.

Testosterone, however, does not simply surge after menopause. Circulating androgen levels generally decline with age.

What changes is the balance between oestrogen and androgen activity.

This is sometimes described as relative hyperandrogenism.

That sounds dramatic, but it does not mean your body has suddenly started producing abnormally high levels of male hormones.

Does androgenetic alopecia mean my testosterone is high?

No.

This is one of the most important points in the paper.

Women with female androgenetic alopecia often have testosterone levels within the normal laboratory range, and studies have not shown a simple relationship between circulating testosterone and who develops female pattern hair loss.

The review also notes that total testosterone is usually within the normal range in postmenopausal women with female androgenetic alopecia.

So if you have typical female pattern hair loss and no other signs of androgen excess, you do not usually need to ask your GP to add a testosterone test to your next blood tests simply because of this diagnosis.

A normal testosterone result would not rule female pattern hair loss out.

So what do androgens have to do with it?

Testosterone can be converted in tissues into a more potent androgen called dihydrotestosterone, or DHT, by the enzyme 5-alpha-reductase.

In susceptible scalp follicles, androgen signalling can influence the pathways that control the hair cycle and contribute to progressive miniaturisation.

The important point is that follicular sensitivity matters.

Two women can have similar hormone blood tests but very different hair.

What role does oestrogen play?

Oestrogen appears to have an important relationship with the hair follicle, although the science is not completely settled.

The review describes evidence that estradiol may support the active growth phase of the hair cycle and may also influence the way androgens are handled within the follicle.

This means that the sharp fall in oestrogen after menopause may help explain why female pattern hair loss becomes more common.

But I would not describe female pattern hair loss as simply an “oestrogen deficiency” problem.

The biology is more complex than that.

Progesterone may also play a role, because it can reduce ovarian androgen production and may reduce DHT formation. The fall in progesterone after menopause may therefore contribute too.

Is this just ageing?

Not entirely.

Ageing itself changes the hair.

Hair density tends to reduce with age, and age-related changes can exist alongside female pattern hair loss.

The review discusses evidence that ageing is associated with reduced hair density, while menopause may also affect hair growth and the proportion of follicles in active growth.

So when a woman in her 50s, 60s or 70s notices thinning, it should not automatically be dismissed as “just ageing”.

There may be a recognisable hair-loss condition present.

What about weight, insulin resistance and metabolism?

The review also highlights another interesting area.

Several studies found associations between female androgenetic alopecia and higher BMI, insulin resistance, higher fasting glucose and metabolic syndrome.

That does not mean weight causes female pattern hair loss.

It does suggest that the condition is influenced by a wider biological environment involving hormones, metabolism and inflammation.

Again, this supports the main message of the paper:

female pattern hair loss is not simply a testosterone problem.

Will HRT treat my hair loss?

At the moment, we do not know.

The authors specifically state that there are currently no clinical data showing how hormone replacement therapy affects the hair-follicle cycle in postmenopausal women.

There are theoretical reasons why oestrogen and progesterone might help support the follicle, but that is not the same as having evidence that HRT is an effective treatment for female androgenetic alopecia.

So I would not recommend HRT specifically as a hair-loss treatment on the evidence we currently have.

So why has this happened to me?

Probably because several things are interacting.

Your follicles have their own susceptibility.

They are ageing.

Your oestrogen and progesterone levels have changed.

The balance between oestrogen and androgen activity has changed.

And metabolism, inflammation and follicular sensitivity may all contribute.

What this diagnosis does not mean is that you suddenly have too much testosterone.

That is the part I think is most important to understand.

Female androgenetic alopecia after menopause is better thought of as a complex interaction between ageing, hormones and the biology of the individual hair follicle.

And once we understand what is happening, we can then talk sensibly about what — if anything — you would like to do about it.

Frequently Asked Questions

Is female androgenetic alopecia the same as female pattern hair loss?

Yes. The terms are commonly used to describe the same process of progressive follicle miniaturisation in women.

Does female pattern hair loss mean I have high testosterone?

No. Most postmenopausal women with female androgenetic alopecia have testosterone levels within the normal laboratory range.

Should I ask my GP to check my testosterone?

Not usually just because you have been diagnosed with typical female pattern hair loss. Testing may be appropriate if there are other signs of androgen excess, but a normal testosterone level does not exclude the condition.

Why did it become noticeable after menopause?

Because the hormonal environment changes. Oestrogen and progesterone fall, while androgen activity becomes relatively more important. Ageing of the follicle may also contribute.

Will HRT regrow my hair?

We do not currently have good clinical evidence showing that HRT treats female androgenetic alopecia.
