Menopause is a natural stage in a woman's life when her reproductive abilities decline and estrogen and progesterone levels fall. This hormonal change causes symptoms in nearly 50% of women, including hair loss. Hair loss during menopause is caused by changes in hormone levels that increase production of DHT, which can damage hair follicles and cause hair to thin. Fortunately, hair loss during menopause is usually temporary, and hormone replacement therapy or reducing stress through lifestyle changes can help minimize its effects.
