The vast majority of women affected fall into the Ludwig I class. The incidence in women has been reported to be as low as eight percent and as high as 87 percent. It does appear to be as common in women as in men. The hair loss in women becomes particularly notable in menopause. Androgens are responsible for hair loss in women by the same mechanisms they cause hair loss in men.
Women do produce small amounts of androgens by way of the ovaries and adrenal glands.
Also prehormones are produced by the ovaries that are converted to androgens outside of the ovaries or adrenal glands. In women, the process of miniaturization of the hair follicle is more random with some hair being unaffected. Normal thick hairs are mixed with finer, smaller diameter hairs. The end result is a visual decrease in density of hair rather than total loss of hair. The hair growth cycle is affected as in men.
