Hair thinning in women can be attributed to hormonal changes, particularly during menopause. Research suggests that the decrease in estrogen and progesterone levels during menopause is related to hair loss. These hormones help in promoting faster hair growth and prolonging the time hair stays on the head. When their levels drop, hair growth slows down, and the hair becomes much thinner. Additionally, the decrease in estrogen and progesterone triggers an increase in the production of androgens, which are male hormones. Androgens can shrink hair follicles, leading to hair loss on the head.
Furthermore, the effects of hormonal changes on hair growth are significant. Hormones have a close association with the hair cycle and hair follicle structure. Many hormones control hair growth, cycle, and density. After menopause, the higher frequency of developing female pattern hair loss indicates that estrogens play a role in the stimulation of hair. The hormonal impact on hair growth and the association of different endocrine disorders with hair changes are well-documented.
In addressing hair thinning caused by hormonal imbalances, bioidentical hormone therapy can be considered. This therapy aims to bring estrogen and progesterone levels back into balance, potentially helping with hair thinning caused by hormonal changes. Therefore, hormonal changes, particularly the decrease in estrogen and progesterone levels during menopause, play a significant role in hair thinning in women, and addressing these hormonal imbalances may help mitigate this issue.
