Thinning hair in menopause: causes and what actually helps

Name: Thinning hair in menopause: causes and what actually helps
Creator: MenoWoman

Hair thinning around menopause is common and is usually female pattern hair loss, made more noticeable as estrogen falls. Topical minoxidil is the treatment with the best evidence, while rosemary oil and biotin have little to show for women.

See a doctor or dermatologist if hair falls out suddenly or in clumps, or you notice patchy bald spots. A red, sore or scaly scalp also needs checking. A doctor can also check for treatable causes such as thyroid problems or low iron.

What it is and how common it is

Thinning hair often shows as a wider part, less volume on top or a smaller ponytail. More than half of women notice hair loss at some point.¹

The most common type is female pattern hair loss, which thins hair over the top and sides of the scalp.¹ A 2022 study of 178 women at a menopause clinic found it in 52% of them. It was more common with older age and higher body weight.²

Many women also find their hair gets drier, finer and more brittle.³

Why it happens in menopause

Estrogen helps keep hairs in their growing phase. As levels fall, the growing phase gets shorter and regrowth slows.³

Androgens, such as testosterone, then have relatively more effect on the hair follicles. Over time, some follicles shrink and make thinner hairs.³

Experts are still unsure how much of this comes from menopause and how much from aging and genes.^2,3 A family history of hair loss raises the chance of it.¹

What else can cause it

Hair loss has many causes, and some are easy to treat. A doctor may look for:¹

thyroid problems
anemia or low iron, and low levels of other nutrients such as vitamin D or zinc
shedding after stress or rapid weight loss (telogen effluvium)
medicines, including some blood pressure and gout medicines, and high doses of vitamin A
damage from chemical hair treatments

Tests may include a gentle hair-pull test, a close look at the scalp and blood tests. Sometimes a small scalp biopsy is needed.¹ Hair loss from stress may settle on its own.¹

Everyday measures

Gentle care will not regrow hair, but it can reduce breakage and make hair look fuller.

Use a gentle, moisturizing shampoo and wash a little less often if your scalp is dry.³
Use deep conditioners and limit hot styling tools.³
Cut back on harsh chemical treatments, which can damage hair.¹ If you color your hair, see our guide to gentler hair dyes for gray hair.
Be patient with any treatment. Hair grows slowly, and minoxidil only keeps working while you use it.¹

A dermatologist is the best person to diagnose the type of hair loss and plan treatment.¹

What helps: options rated

Option	Evidence	What the research shows
Topical minoxidil	Strong evidence	In a Cochrane review, women using minoxidil were about twice as likely as those on placebo to report clear regrowth. The 2% and 5% strengths worked about equally.⁴ It is FDA-approved for female pattern hair loss, must be used continuously and is not for use in pregnancy.¹
Treating an underlying cause	Some evidence	When tests find a thyroid problem or a nutrient deficiency, treating it is part of standard care for hair loss.¹
Gentle hair care	Some evidence	Doctors advise avoiding damaging products and harsh styling, since these are known causes of hair loss. It reduces breakage rather than regrowing hair.^1,3
Other prescription medicines	Weak evidence	Spironolactone and similar medicines are sometimes prescribed, but the Cochrane review found too few good trials. Finasteride worked no better than placebo in women.⁴
Rosemary oil	Weak evidence	Evidence rests on one six-month trial of 100 men, where hair counts rose about as much as with 2% minoxidil.⁵ It has not been tested in women with menopausal hair loss.
Biotin supplements	Weak evidence	There is virtually no evidence that biotin improves hair in people who are not deficient. The FDA has warned it can distort blood tests, including thyroid and heart tests, so tell your doctor if you take it.⁶
