Abstract

Hair infection by fungal agents, also called trichomycoses, is one of the common concerns in human beings. The common agents causing hair infections are dermatophytes, Malassezia species and those causing piedra. The former two can give rise to considerable discomfort and also cause immune-mediated reactions in the form of kerion and dermatophytids. The etiopathogenesis of trichomycoses, along with its clinical aspects and the management, are briefed here.

Keywords: Malassezia folliculitis; piedra; tinea capitis; trichomycoses.
