L73: Other follicular disorders

L73.1: Pseudofolliculitis barbae

Every hair is anchored in a small bulb, the hair follicle. Sebaceous glands are usually attached to these hair follicles. The sebaceous glands produce an oily substance for the skin called sebum. Sebum prevents the skin from drying out.

Hairs have grown into your skin. This can occur after shaving, for example. When hair grows into the skin, the skin can become inflamed. Those areas can become red and swollen. Small white spots are usually visible in the pores of the skin. The inflammation causes sebum to accumulate in the pores.
