What should you know about ingrown hair and keratosis pilaris?

An ingrown hair is linked to a hair curling into skin, often after shaving or waxing, and may form a local red or tender bump. Keratosis pilaris is a rough, follicle-based pattern caused by keratin plugging follicles, often on the upper arms, thighs, or cheeks. It commonly feels like fine sandpaper and may affect many follicles. A clinician can tell whether one or both processes are present.

Use a fragrance-free moisturiser or emollient therapy regularly and avoid harsh scrubs. For keratosis pilaris, a clinician may recommend a suitable exfoliating product or topical retinoid. Do not squeeze individual bumps. If shaving worsens ingrown hairs, pause until the skin calms and change technique; laser hair removal or a chemical peel may be discussed for selected cases by a qualified professional.

Seek review when bumps are painful, pus-filled, rapidly changing, intensely itchy, or leaving significant marks. Also arrange an appointment when home care does not clarify the pattern. Redness spreading with fever needs prompt attention because infection requires different care from keratosis pilaris.

Ask which condition best explains the distribution and texture, how often to moisturise, and whether a retinoid or other exfoliating treatment is appropriate. Discuss safe hair-removal options if shaving triggers separate ingrown hairs.
