Types of Folliculitis
Cutting oil folliculitis
Is folliculitis contagious?
Paraffin-based ointments, moisturisers, and adhesive plasters may all result in a sterile folliculitis. If a moisturiser is needed, choose an oil-free product, as it is less likely to cause occlusion.
Coal tar, cutting oils and other chemicals may cause an irritant folliculitis. Avoid contact with the causative product.
Overuse of topical steroids may produce a folliculitis. Perioral dermatitis is a facial folliculitis provoked by moisturisers and topical steroids. Perioral dermatitis is treated with tetracycline antibiotics for six weeks or so.
Folliculitis due to drugs
Folliculitis may be due to drugs, particularly corticosteroids (steroid acne), androgens (male hormones), ACTH, lithium, isoniazid (INH), phenytoin and B-complex vitamins. Protein kinase inhibitors (epidermal growth factor receptor inhibitors) and targeted therapy for metastatic melanoma (vemurafenib, dabrafenib) nearly always result in folliculitis.
Folliculitis affecting the buttocks is quite common and is often nonspecific, ie no specific cause is found. Buttock folliculitis is equally common in males and females.
- Acute buttock folliculitis is usually bacterial in origin (like boils), resulting in red painful papules and pustules. It clears with antibiotics.
