What should you know about folliculitis: how to prevent it?

Folliculitis develops when hair follicles become inflamed. Repeated rubbing from tight clothes or equipment, trapped sweat, shaving, waxing, ingrown hairs, oily products, and warm shared water can all play a part. The right prevention plan depends on the pattern: bumps after hair removal suggest a different trigger from spots under swimwear after a spa visit.

Itch, redness, tenderness, and small pimples can overlap with other conditions. A recurring rash should be identified rather than treated with increasingly harsh cleansers.

Shower after heavy sweating, change out of damp clothing, and choose breathable fabrics. Wash sportswear, towels, and razors regularly; do not share them. Use a clean, sharp razor, shave in the direction of hair growth with lubrication, and avoid repeated passes over the same patch. If shaving repeatedly causes [Ingrown Hairs](/symptoms/ingrown-hairs/), discuss another hair-removal method.

Choose non-comedogenic products when possible and stop any cleanser that leaves burning or tightness. Rinse after swimming and change wet swimwear promptly. If prevention does not control recurrent bumps, a clinician may discuss [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or another targeted plan.

Book a medical review for repeated episodes, scarring, deep painful lumps, scalp involvement, or a rash that continues despite removing obvious triggers. Seek prompt care for rapidly spreading redness, severe pain, fever, or feeling unwell; these features need assessment for a more significant infection.

Which trigger best fits my pattern? Should I change my shaving or hair-removal method? Is a medicated wash appropriate? Could this be [Pimples](/symptoms/pimples/) or another condition rather than folliculitis?
