Razor Bumps (Pseudofolliculitis Barbae):
Information for adults

Razor bumps (pseudofolliculitis barbae), also known as shaving bumps, affects men with tightly curved (or curly) hairs. When the tip of hair grows back under the skin or into the hair follicle, it is known as ingrown hair. If ingrown hair causes a reaction in the skin, it is known as razor bumps. Razor bumps is not an infection but rather a "foreign body" reaction, much like the body would react to a splinter of wood in the skin. The condition may be worsened by methods used to achieve a close shave, such as pulling the skin tight while shaving, shaving against the "grain" or direction of hair growth, or using multi-blade razors.
