It is probably the best kept secret: hair loss in females is a common thing. As mentioned above, the most common type of women's hair loss is androgenetic alopecia. The female pattern baldness is seen as hair thinning predominantly over the tope and sides of the head. Androgenetic alopecia in women is most commonly seen after menopause, although it may begin as early as puberty. How can you be sure that you're not actually experiencing hair loss? Normal hair falls approximately 100-125 strands per day, true hair loss occurs when the loss is not replaced or when the daily hair shed exceeds 125.
Suddenly hormonal changes when starting or stopping contraceptives, starting or ending a pregnancy, the start of menopause, all has been characterized as the promoter of androgenetic alopecia. The two key events in a life of a woman might promote this onset: pregnancy and menopause. WHY? Simply because menopause causes permanent changes in hormone production, the adrenal glands also undergo changes during menopause. the overall result is a reduction of "androgen antagonist" such as estrogen and a net increase in androgen, as we have elaborated before, androgen is directly responsible in hair loss.
