Razor bumps on the scalp

Ingrown hairs commonly present as razor bumps when a short hair re-enters the skin instead of growing outward. Clippers, repeated passes, sweat, helmets and shirt collars can irritate follicles. Folliculitis may cause multiple inflamed or pus-filled spots. Persistent bumps with scarring or areas of hair loss need a clinician’s assessment because shaving may not be the only cause.

Stop close shaving until the spots calm down and clean clippers before using them again. Wash the scalp gently, rinse away sweat, and avoid scratching or picking. Do not share razors, clippers, towels or hats while bumps are inflamed. Use a guarded trimmer and leave more length when you resume grooming. A dermatologist can advise on medicated cleansing or other treatment, and can discuss Laser Hair Removal for suitable recurring areas.

Arrange an appointment for recurrent scalp bumps, pus, crusting, bleeding, scarring, tender deep lumps or patchy hair loss. Seek prompt care if redness spreads, pain becomes severe or fever develops. A rash that extends beyond shaved skin or persists despite stopping shaving should also be examined.

Is this an ingrown hair or folliculitis? Could the bumps damage follicles or cause scarring? Which clipper length and cleanser should I use? What should I do if hair loss appears?
