Is there non bacterial folliculitis and what are the causes?

Folliculitis is the medical term for inflamed hair follicles. The inflammation can be caused or complicated by an infection or have a non-infectious cause. In addition to bacterial folliculitis, fungi and herpes simplex viruses can also infect hair follicles. A condition called eosinophilic folliculitis is non-infectious cause, which occurs primarily in immunocompromised people. Conditions that can mimic folliculitis and/or predispose a person to folliculitis include impetigo, eczema and psoriasis.
