Excess hair is a common condition in both men and women, and is most common in skin types from a Mediterranean, Middle Eastern and South Asian background.
Excess hair in men may not have an identifiable cause, however excess hair growth in women is called hirsutism. The hair is usually thick and dark, rather than fine and fair. The excess hair growth is usually on parts of the body where hair does not normally grow, such as the face and chest. Excess hair growth can also be a side effect of PCOS.
Hirsutism is caused by an excess of male sex hormones called androgens, testosterone is the best known androgens. Hirsutism can be caused either by the high level of androgens, or by the hair follicles being more sensitive to normal androgen levels.
