There are many reasons for women’s serious hair loss, such as androgenetic alopecia, endocrine disorders, mental stress, malnutrition, scalp diseases and other reasons. 1. Androgenetic alopecia: there is a certain genetic predisposition, and the female body androgen secretion is exuberant, which will cause the hair follicles to be miniaturized, the hairs in the anagen phase will gradually become thin, and eventually the hair follicles will shrink and disappear, causing hair loss. 2. Endocrine disorders: for example, a woman’s hormone metabolism is severely affected during pregnancy, which may lead to hair loss. 3. Mental stress: women are prone to stress, depression and anxiety, which can also cause severe hair loss. Staying up all night and working hard may also cause women to lose their hair. 4.
