What should you know about small white bumps after shaving?

A close shave can irritate the opening of a hair follicle. A hair that curves back into the skin may create an ingrown hair, often with a central hair, itch, or tenderness. Pus-topped bumps around several follicles can occur with folliculitis. Razor bumps, also called pseudofolliculitis barbae, are especially common where coarse or curly hair is shaved close and repeatedly grows into the skin. Rough, uniform bumps away from shaving areas may instead fit keratosis pilaris.

Pause shaving over active bumps until the skin settles. Use warm water, a gentle cleanser, and a clean sharp razor; shave in the direction of hair growth with light pressure and as few passes as possible. Do not squeeze, dig for, or pull out trapped hairs with unclean tools. Loose clothing can reduce rubbing on body areas. If bumps recur despite technique changes, a clinician can discuss topical care or laser hair removal as a longer-term hair-reduction option.

Arrange a review if bumps persist, recur after most shaves, leave dark marks or scars, or spread beyond the shaved area. Seek prompt care for rapidly increasing redness, warmth, swelling, pus, severe pain, or fever. A clinician can check whether folliculitis, ingrown hairs, razor bumps, or another condition is responsible before prescribing treatment.

Are these ingrown hairs, folliculitis, or razor bumps? Should I change my shaving method or hair-removal routine? What can prevent dark marks, scarring, and repeated flare-ups?
