Thinning Hair · Hormonal
Menopause and Hair Loss
Hair thinning is one of the most common symptoms of menopause. It is also one of the least talked about.
Most women expect hot flushes. Many know about sleep changes and mood shifts. Fewer are prepared for what happens to their hair. Yet hair thinning affects the majority of women at some point during perimenopause or in the years that follow. It tends to come on gradually, which makes it easy to dismiss for a long time before it becomes impossible to ignore.
The good news is that menopausal hair loss is one of the more treatable forms of hair thinning. The sooner it is properly assessed, the more options there are.
What Menopause Does to Your Hair
During perimenopause and menopause, levels of oestrogen and progesterone fall. Both hormones play a role in the hair growth cycle: they help extend the active growth phase and support follicle health. As they decline, the effects of androgens (male hormones that women naturally produce in small amounts) become more pronounced.
The follicles most sensitive to androgen activity begin to shrink. The hairs they produce become progressively finer and shorter. The active growth phase shortens. Over time, this process, known as follicle miniaturisation, leads to visibly reduced density across the crown and parting. This is female pattern hair loss, and menopausal hormonal change is one of its most common triggers.
What Treatment Can Do
Two medications in particular have the strongest published evidence for female pattern hair loss in women: minoxidil and spironolactone. Used together, they address the condition from two directions at once.
Minoxidil
Minoxidil works by stimulating dormant follicles and extending the active growth phase of hair. It increases blood flow to the follicle, encourages hairs to re-enter growth, and over time improves density. It is the only medication specifically approved by the FDA for hair loss in women. Harvard Medical School notes that published research has confirmed minoxidil's ability to stimulate hair growth in women with pattern hair loss.
Spironolactone
Spironolactone works on the hormonal side of the problem. It reduces the influence of androgens on the hair follicle, slowing the miniaturisation process that drives progressive thinning. A 2023 systematic review published in PMC concluded that spironolactone improved hair density and reduced hair loss in women with female pattern hair loss, with no major safety concerns reported in most studies.
Why the combination works
On their own, each medication addresses a different part of the problem. Minoxidil stimulates growth. Spironolactone slows the hormonal cause. Together, they tackle both at once, which is why the combination consistently outperforms either treatment used alone.
The Clinic's Prescribed Combination
Spiroxidil
At UK Women's Hair Loss Clinic, we prescribe spironolactone and minoxidil together as Spiroxidil, a combination treatment available to suitable patients following a consultation with one of our hair loss doctors.
A study by Professor Rodney Sinclair found that a combination of low-dose oral minoxidil and spironolactone was safe and effective for women with female pattern hair loss. More recent clinical research published in 2025 showed that adding spironolactone to minoxidil therapy produces greater improvements than minoxidil alone.
Spiroxidil is a prescription-only treatment. Whether it is appropriate for you depends on your hair loss pattern, your medical history, and other individual factors. A consultation with one of our doctors is the right starting point.
What to Expect From Treatment
Hair does not respond to treatment quickly. The women who see the best results are those who stay consistent and give it enough time to work.
Results vary between individuals. The timeline above reflects the typical experience but is not a guarantee of outcome for any individual patient.
