Hair removal for keratosis pilaris: what to know

Keratosis pilaris forms when keratin plugs block hair follicles, often on the upper arms, thighs, cheeks or buttocks. Shaving, waxing and friction can leave the area more inflamed, while picking can cause marks. A new red bump after hair removal may also be an ingrown hair, which is different from the small, rough follicular plugs of keratosis pilaris. See [Keratosis Pilaris](/conditions/keratosis-pilaris/) and [Skin Bumps](/symptoms/skin-bumps/) for context.

If you shave, soften the hair first, use a clean sharp razor, shave in the direction of growth and avoid repeated passes over bumps. Do not scrub aggressively or wax skin that is irritated. Apply a plain moisturiser after washing; [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) helps support the skin barrier. A clinician may suggest urea, lactic acid or [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) for follicular plugging. [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) or a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) may be considered only after assessing skin tone, sensitivity and active inflammation.

Arrange review when bumps are painful, pus-filled, rapidly spreading, very itchy or leaving persistent dark marks. Seek advice before treatment if the skin is sunburned, cracked or infected. A clinician can distinguish keratosis pilaris from folliculitis or [Ingrown Hairs](/symptoms/ingrown-hairs/) and adjust the plan.

Are these bumps keratosis pilaris or ingrown hairs? Which hair-removal method is least irritating for my skin? Should I stop acids or retinoids before a session? What should I use if redness or darkening follows treatment?
