As estrogen falls through the transition, the balance between estrogen and androgens shifts, and for many women that shows up as gradual hair thinning. Estrogen is broadly hair-friendly - it is part of why hair can feel fuller in some life stages - so its decline, combined with the relatively greater androgen influence that follows, tends to work against the hair.
This is genuinely common and genuinely under-discussed, which is why so many women are blindsided by it. The companion read from the menopause side is HRT and hair thinning.
