Scalp

scalp the integument covering the top of the head. It consists of three layers of tissue: the skin, an underlying layer of tissue and blood vessels, and the occipitofrontalis muscle stretching from the eyebrows to the back of the head. Except for its abundant growth of hair, the skin of the scalp resembles that of the rest of the body but is especially rich in blood vessels. Hence profuse bleeding may be associated with scalp injuries.

Hirsutism

Hirsutism is a condition of unwanted, male-pattern hair growth in women. Hirsutism results in excessive amounts of coarse and pigmented hair on body areas where men typically grow hair — face, chest and back. The amount of body hair you have is largely determined by your genetic makeup. Hirsutism may arise from excess male hormones called androgens, primarily testosterone. Or hirsutism may be due to an ethnic or family trait.
