What causes female hair thinning, and how do menopause and PCOS affect it?
Short answer
Female hair thinning often involves inherited traits and changes in how hair follicles respond to hormones. It becomes more common with age, including around menopause. PCOS can also contribute, especially with irregular periods or acne. Not all women with thinning hair have high hormone levels or PCOS.
Female pattern hair thinning is linked to inherited traits, aging, and hormone effects on hair follicles. Over time, affected follicles may produce finer, shorter hairs. This can make the part look wider and reduce volume on top of the scalp.
Thinning often becomes more noticeable around menopause. Still, a change in hair volume does not prove that menopause is the only cause. Thyroid disease, low iron, certain medicines, and other health issues may also play a role. Many women with female pattern hair loss have hormone levels within the normal range.
PCOS, or polycystic ovary syndrome, can involve higher levels of androgen hormones. Along with scalp thinning, signs may include irregular periods, acne, or extra facial hair. Hair thinning alone cannot confirm PCOS. Tell your physician if these symptoms are new or changing quickly. A licensed physician in your state can review the full picture and decide whether testing, an in-person exam, or treatment is appropriate.
