Med. Presence of less than the normal amount of hair, or similarly fur

Hypotrichosis is a condition of abnormal hair patterns - predominantly loss or reduction. It occurs, most frequently, by the growth of vellus hair in areas of the body that normally produce terminal 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. 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. The opposite of hypotrichosis is hypertrichosis, where terminal hair grows in areas that would otherwise normally have vellus hair, for example abnormally thick facial hair growth in women. Genetic forms of localized autosomal recessive hypotrichosis include:
