hair follicle
Scalp's tiny tunnel
A hair follicle is the small cavity in the skin from which a hair grows.
Each follicle contains the root of a single hair and the cells that produce it.
Follicles determine hair texture—their shape affects whether hair grows straight or curly.
The dermatologist examined the damaged hair follicles.
