Terminal Hair Growth

Meaning

Terminal hair growth refers to the development of thick, long, and pigmented hair that replaces fine, non-pigmented vellus hair, typically occurring in response to androgenic hormone stimulation during puberty and throughout life. This type of hair is characteristic of the scalp, eyebrows, and adult secondary sexual hair patterns on the body. The transition from vellus to terminal hair is a classic clinical indicator of androgen action on the pilosebaceous unit.
