What should you know about razor bump care?

After a close shave, a shortened hair can curve back toward the skin and trigger a small inflammatory response. Tight clothing, rubbing, sweat, and repeated shaving can keep the area irritated. Some bumps have a rough texture and may instead reflect keratosis pilaris; others become inflamed around the follicle, as in folliculitis. A clinician can check persistent bumps for pseudofolliculitis barbae or another skin problem.

Stop shaving the affected patch briefly and cleanse with lukewarm water and a mild, non-scrubbing product. Use a warm compress for comfort, then leave any visible hair to emerge naturally. Avoid tweezing, scraping, harsh exfoliation, and fragranced products on broken skin. For prevention, soften hair before shaving, use shaving gel, make one light pass in the direction of growth, rinse the blade often, and moisturise afterwards. If shaving continues to trigger bumps, ask about laser hair removal.

See a dermatologist if bumps persist despite gentler shaving, recur in the same sites, form pus, become increasingly sore, or leave scars or lasting colour changes. Prompt assessment is needed for rapidly spreading redness, fever, or a deep lump. Treatment depends on whether the main problem is an ingrown hair, follicle inflammation, or infection.

What is driving my bumps: trapped hairs, folliculitis, or keratosis pilaris? Which cleanser or prescription product is suitable? Should I change hair-removal methods?
