Itchy pubic hair accompanied by pimples is usually a case of folliculitis or eczema that brings on itchy pubic skin and requires a visit to a hospital dermatologist to confirm the diagnosis and determine the cause and treat the symptoms. Folliculitis of the pubic area is characterised by red, swollen and painful skin around the opening of the hair follicles on the pubic skin.
Often poor hygiene practices can increase the chance of microbial invasion, which can lead to bacterial infection of the hair follicle and trigger folliculitis in the pubic area.
