Hirsutism is a condition in which women grow thick, black hair similar to that of men on their face, chest, abdomen, and back. The main causes of this are:
PCOS: The most important cause of excessive hair growth is polycystic ovary syndrome. Due to hormonal imbalance in the body, the level of androgen (male hormone) increases, which causes unwanted hair growth and menstrual irregularities.
Hormonal changes: Changes or tumors in the adrenal glands cause excessive production of androgen hormones. This can lead to hair growth on the face and other areas.
Menopause: During menopause, the level of the female hormone estrogen decreases. Due to the increased influence of male hormones in the body during this time, some people start to see hair on the chin and upper lip.
Side effects of medications: The use of medications containing steroids and medications taken as part of hormone therapy can affect the body’s natural hormone levels and lead to excessive hair growth.
Heredity: If your mother or sisters have this type of excessive hair growth in your family, it can be passed on genetically to the next generation. Some ethnic groups are born with excessive hair growth.
