Infection can spread and become non-healing and hard sores. Common causes of folliculitis are bacterial or fungal infection. ‘Follicle’ is a small hole or sac which is a part of skin where hair grows and into this sac, sebaceous glands open. “Itis” means inflammation (redness and swelling). Apart from bacterial or fungal infection, inflammation may also occur due to viral infection, inflammation from Ingrown Hairs, irritation by clothes, chemical substances, razors, waxes etc. Common bacterial infection is caused by Staphylococcus aureus that present on the skin, but cause swelling and redness of hair follicles when they get into the body through cuts. Hot tub baths may also cause folliculitis because of infection of bacteria called pseudomonas folliculitis present in hot tub.Where Does Folliculitis Occur?

The most common areas where it occurs is scalp where follicles are densest, face, chest, back, thighs, buttocks and groin area.

For example, sharing the razor, towels or clothes of the person affected by folliculitis may cause the other person also to have folliculitis. Persons using Jacuzzi or bath tubs of affected people can be affected by folliculitis.DiagnosisFolliculitis can be diagnosed by physical examination of skin. Sometimes microbial culture may help in the diagnosis of folliculitis. Infected hair can be examined under microscope to detect fungal infection. Skin biopsy may also be done for diagnosing folliculitis.What Is The Treatment For Folliculitis?
Folliculitis is seen in people who may not have any other disease or illness. Most cases of folliculitis clears up on its own without treatment in few days and others are easily treatable with over-the-counter medications like benzoyl peroxide, chlorhexidine.
