Many women notice changes in their hair in midlife — more shedding, thinning, a different texture, or new facial hair — and in their skin, such as dryness, itching, or less elasticity. These changes can feel distressing in a way that's easy to underestimate. Menopause is one possible context for them — not the only one, and not a diagnosis. Hair can also change after illness, stress, surgery, new medications, or with thyroid or iron problems, and skin with age, sun exposure, and skin conditions, which is why the pattern of change matters.
Hair thinning
Hair thinning is plausibly linked to menopausal hormone shifts, but the underlying pathway is more complex than a simple androgen effect, and evidence is largely correlational.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Hair loss and menopause
Female pattern hair loss and frontal fibrosing alopecia (a scarring type of hair loss) are both seen more often in the years around and after menopause. This is an association from mostly observational studies — it doesn't show that menopause causes hair loss in any individual.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Skin changes (dryness, reduced elasticity)
Skin dryness and reduced elasticity are plausibly linked to declining estrogen, with some mechanistic and observational support, but the evidence is mostly from small non-randomized studies rather than controlled trials.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Itchy skin (generalized)
Generalized itchy skin is commonly reported and plausibly linked to menopause via skin dryness, but is usually studied as a downstream effect of dryness rather than as its own distinct, guideline-recognized symptom.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Increased facial hair
Increased facial hair after menopause is a well-established, clearly mechanistically explained pattern in endocrinology literature, distinct from hirsutism caused by other hormonal conditions.
Multiple high-quality studies generally point in the same direction, though no study can guarantee an individual outcome.
Researchers don't yet know how much falling hormone levels, rather than age, genetics, or other health factors, drive hair thinning in any one woman. Studies of menopausal skin change face similar limits, with age and sun exposure hard to separate from hormones. Most hair-treatment trials are small, short, and rarely include postmenopausal women specifically, and with multi-ingredient "hair" supplements it's often impossible to tell which ingredient, if any, caused a reported result. "Insufficient evidence" here means a question hasn't been answered well — not that an option has been proven not to work for anyone.

Topical minoxidil
Topical minoxidil is among the best-studied treatments for female pattern hair loss: in pooled placebo-controlled trials, roughly twice as many women reported moderate-to-marked regrowth with minoxidil as with placebo. Results vary, improvement typically takes at least six months, and a clinician can help confirm whether it fits the type of hair loss you have.
There is reasonably consistent research, but important limitations or unanswered questions remain.
Oral minoxidil
Low-dose oral minoxidil is prescribed off-label by some clinicians for hair loss. A 2025 meta-analysis of four randomized trials (279 adults with pattern hair loss) found hair density similar to topical minoxidil, but unwanted hair growth elsewhere on the body was about twice as common with the oral form. Whether it's appropriate depends on your health history and other medicines — a decision for a clinician.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Anti-androgens (e.g. spironolactone)
Some clinicians use anti-androgen medicines such as spironolactone for selected women with pattern hair loss, but research is limited and mixed: a small 2025 placebo-controlled trial in premenopausal women found a modest added benefit alongside minoxidil, with menstrual irregularities common. Finasteride 1 mg did not outperform placebo in women in pooled trials. Results for one medicine, dose, or age group don't automatically apply to others, and these medicines have important safety and monitoring considerations.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Hormone therapy
Menopausal hormone therapy is not an established treatment for hair loss and isn't indicated for hair loss alone. Frontal fibrosing alopecia is often diagnosed after menopause, and some studies have linked it with hormone therapy, but that research is limited, inconsistent, and mostly involved older formulations — it doesn't show that hormone therapy causes it. Decisions about hormone therapy are based on menopausal symptoms, risks, and benefits, not on an expectation that it will treat hair loss.
Insufficient or very uncertain research for a health-effect claim. It's included because people ask about it, not because it's established care.
What does this grade mean?Biotin
Biotin is essential when a true deficiency is present, but taking biotin has not been shown to improve hair growth for people who aren't deficient.
Insufficient or very uncertain research for a health-effect claim. It's included because people ask about it, not because it's established care.
What does this grade mean?Biotin and lab tests
Some high-dose biotin supplements, common in "hair, skin and nails" products, can interfere with certain laboratory tests — including some troponin tests used to detect a heart attack. Not every test is affected. The FDA advises telling your clinician and the lab if you take biotin.
There is reasonably consistent research, but important limitations or unanswered questions remain.
Iron and vitamin D
If testing finds an iron or vitamin D deficiency, treating it is generally supported in people with hair loss. Evidence that these supplements help without a confirmed deficiency is inconsistent — and too much vitamin A or selenium can itself contribute to hair loss.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?Multi-ingredient hair supplements
Reviews of pattern hair-loss treatment describe the evidence for supplements as variable, and no supplement has established evidence for treating female pattern hair loss. When looking at a product's study, it helps to check who was studied, what it was compared against, how long it ran, who funded it, and whether the tested product matches what's sold.
Insufficient or very uncertain research for a health-effect claim. It's included because people ask about it, not because it's established care.
What does this grade mean?PRP and laser therapy
Platelet-rich plasma (PRP) and low-level laser or light therapy show possible benefit: a 2024 meta-analysis of 21 randomized trials in women found PRP improved hair density and thickness, and home-use laser devices increased hair density compared with sham devices in trials of men and women. But protocols, devices, and PRP preparation differ, the best approach isn't standardized, and adding laser to minoxidil showed no extra benefit in a 2025 meta-analysis.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?When to see a clinician
Hair loss has many possible causes. Clinical guidance treats some changes as worth a professional look: heavy shedding a few months after an illness, surgery, or major stress; round or patchy bald areas; scalp redness, scaling, or inflammation; or areas that look scarred, where a dermatologist can help. Blood tests are considered when other symptoms suggest a problem such as thyroid disease or iron deficiency.
Early, limited, mixed, or indirect research. Some people may find this useful, but we can't be confident about the average effect.
What does this grade mean?M-1 can't tell what is causing a change you've noticed, and it isn't looking at what you've logged — only a clinician who can examine you can. These are reasons for a routine appointment, not usually emergencies; for symptoms that are, see when to seek urgent help.
