Glossary Vellus Hair Density

number of fine, short hairs per skin area

Vellus hair density refers to the number of fine, short, and lightly pigmented hairs (vellus hairs) present per unit area of the skin. These hairs are typically less than 2 mm in length and are often found on areas of the body that are not covered by terminal hairs, such as the face and arms. For professionals, assessing vellus hair density can be important in diagnosing and understanding conditions like alopecia or hirsutism.
