What should you know about types of scalp folliculitis?

Folliculitis is inflammation around a hair follicle. On the scalp, small similar bumps may follow sweating, tight headwear, friction, shaving or heavy hair products. Some cases involve bacteria; others are linked to yeast, ingrown hairs or irritation without an infection. Deeper inflammation can form painful lumps and may affect hair growth if it continues.

Itchy scalp, pimples and skin bumps can occur with folliculitis, but those symptoms also have other causes. A clinician may examine the distribution, scale, drainage and hair changes to decide whether testing or a different diagnosis is needed.

Wash gently after heavy sweating, avoid scratching and pause oily styling products or tight headwear that seem to worsen the area. Do not squeeze or share combs, hats or towels while bumps are inflamed. Use only a medicated wash or topical treatment recommended for your pattern; bacterial and yeast-related problems do not respond to the same approach.

A clinician may recommend topical antibiotic therapy for selected bacterial inflammation, or oral antibiotics when infection is more extensive. Follow the prescribed course and return if new bumps continue or hair becomes thinner over affected skin.

Seek prompt assessment for rapidly spreading redness, severe pain, fever, abundant drainage, tender lumps or swollen neck glands. Arrange dermatology review if the problem keeps returning, leaves scars, forms crusts or causes patchy hair loss. Urgent care is appropriate for facial swelling, breathing difficulty or feeling very unwell.

Does the pattern look bacterial, yeast-related, irritant or linked to ingrown hairs? Should I change my shampoo or styling products? Would a topical treatment be enough, and what signs suggest deeper infection or scarring?
