Androgenetic alopecia (female pattern baldness) is definitely not a privilege of men. It reaches up to 50% of women and is usually attributed to other factors. Until recently the treatments and diagnoses were wrong but nowadays specialists can help a lot.
About 25% of 30-year-old women already show signs of baldness. After 45 years, the rarefaction of hair is more visible.
Evaluating the cases of women who have diffuse hair loss, 20% have baldness. Among men, these percentages reach about 85% with rarefaction of hair.
Baldness is caused by genetic and hereditary factors. Receptors in the roots of hairs bind with fractions of the male hormones that circulate in the body. In women, the main source of these hormones are the ovaries and supra renal. Testosterone, through the enzyme 5 alpha-reductase, is converted to dihydrotestosterone and binds to the hair follicle (root) receptor. The characteristic of this hair loss is the miniaturization of the threads. The hair tones, loses color, and reduces its length until they become a velus. Hair falls small.
