Women produce a small amount of androgen with the ovaries and the adrenal gland. Androgens are responsible for hair loss in women through the same mechanism that creates hair loss in men. Apart from ovaries and adrenal glands, prehormones converted to androgens are also created in ovaries. Women rarely lose their entire hair in one area due to female pattern hair loss. If they lose, another underlying pathological cause should be sought. In women, the development of hair follicle miniaturization, with implanted hair areas, is more rare. Normal thickness hair is found mixed with thin, small diameter hair. For this reason, female type hair loss; it is a decrease in hair density rather than total hair loss. The hair growth cycle is affected as in men. The growth (anagen) phase is shortened, short hair is increased, and the rest (telogen) phase is increased, and hair thinness is observed. If hair loss is thought to be due to abnormal low or excess hormone, hormone levels should be measured.
