Although balding is more of an overtly male disease, according to the American Hair Loss Association, women actually make up 40 percent of hair loss sufferers. And just so you know, a hair grows about a half-inch per month from its follicle. Each individual hair grows for two to six years, rests, falls out, then new hair grows in its place. Unfortunately, sometimes, when a hair falls out, a new hair does not grow.
In what is called female pattern baldness, the cause of this inability to grow new hair is not well understood, but likely has to do with genes, aging and levels of endocrine hormones. The hormonal process of testosterone converting to dihydrotestosterone (DHT) -- which occurs in men and women -- damages the hair follicles. Note: All you need to remember as you're reading this is that DHT is not your friend because it triggers hair loss and inhibits hair growth.
