Folliculitis mostly occurs due to bacterial or fungal infections. It is a common skin condition and is classified as superficial and deep folliculitis. The superficial inflammation of hair follicles caused by a yeast infection is referred to as Pityrosporum folliculitis. Red itchy bumps are usually formed on the chest, face, upper arm, and neck. The dermatologist provides you with oral antifungal medication or antifungal creams and shampoos to treat such folliculitis caused by yeast infection.
