What should you know about folliculitis on buttocks and thighs?

Follicles on the buttocks and thighs can become irritated where skin rubs against skin or clothing. Heat, sweat, shaving, waxing, and occlusive fabrics may add to the problem. Bumps can be itchy, rough, red, or sore and may appear in patches. They can resemble [Ingrown Hairs](/symptoms/ingrown-hairs/) or other [Skin Bumps](/symptoms/skin-bumps/), so persistent or unusual changes deserve an examination.

Shower after heavy sweating, dry the folds carefully, and wear clean, breathable clothing. Pause hair removal over active bumps. Avoid vigorous scrubbing, picking, and thick products that trap heat. A clinician may choose [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) when bacterial infection is present; more extensive infection may require [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/).

Seek medical advice if the rash spreads across both areas, returns often, drains, scars, or interferes with movement. Get prompt care for rapidly spreading redness, increasing heat, severe tenderness, fever, or a growing deep swelling. These features can indicate a problem needing more than home skin care.

Does the distribution suggest friction, hair removal, bacteria, or another rash? Should I alter exercise clothing or washing habits? What should I do if the bumps leave dark marks after healing?
