Gram-negative folliculitis is the word used to describe any inflammation of one or more hair follicles anywhere in the skin. The disorder is caused by damage to the follicles, by a blocked follicle, by shaving, or by friction caused by clothing, helmet straps, and the like. Hair follicles in the neck, groin, or genital area are particularly susceptible to inflammation.
These most frequently appear in the neck, groin, or genital areas. In some cases, the pimples may develop a crust. Folliculitis starts when hair follicles are damaged by friction from clothing, blockage of the follicle, or shaving. In most cases of Gram-negative folliculitis symptoms, the damaged follicles are then infected with the bacteria Staphylococcus (staph). Barber's itch is a staph infection of the hair follicles in the beard area of the face, usually the upper lip. Tinea barbae is similar to barber's itch, but the infection is caused by a fungus.
The signs and symptoms of Gram-negative folliculitis are varying. It’s depending on the type of infection. In superficial forms of the disorder, small pimples develop around one or more hair follicles. It then turns into a small, raised area of skin that contains pus and often itches or burns. When these pustules break open, they may drain pus and or blood.
Acne of any form can be irritating, but scalp acne is technically known as scalp folliculitis that can be downright annoying. If you develop an infection of your scalp's hair follicles, you can do a number of things to treat it, with a focus on keeping your hair and scalp clean, and controlling oily hair before it gets out of hand. Always wash your hair in either lukewarm or cold water as hot water usage results in over-production of sebum and your scalp will be oily in a few hours.
