1. An abnormal hairiness; especially, an adult male pattern of hair distribution in women.

A woman whose hirsutism is not hormone-related has long, fine hairs on her face, arms, chest, and back.

2. Heavy growth of hair, often in an abnormal distribution or place.

This condition is defined as excessive and increased hair growth on women in locations where the occurrence of terminal hair normally is minimal or absent.

It refers to the male pattern of body hair and it is therefore primarily of cosmetic and psychological concern.
