Hypotrichosis is a condition of abnormal hair growth. It occurs, most frequently, by the growth of terminal hair in areas of the body that normally produce vellus hair. Typically, the individual's hair growth is normal after birth, but shortly thereafter the hair is shed and replaced with sparse, abnormal hair growth. The new hair is typically fine, short and brittle, and may lack pigmentation. Baldness may be present by the time the subject is 25 years old.[1]

Hypotrichosis is a common feature of Hallermann-Streiff syndrome as well as others. It can also be used to describe the lack of hair growth due to chemotherapy.
