According to DermNet NZ, treatment options for pseudofolliculitis barbae include use of a polyester cleansing pad, use of a single-blade razor or electric hair clippers, and lotion containing glycolic acid. Severe cases may be treated with topical acne creams or oral antibiotics. Use of laser hair removal in place of shaving may be the most effective treatment.
According to Wikipedia, the simplest solution to pseudofolliculitis barbae is to let the beard grow, at least to the stubble stage. Avoiding shaving for up to four weeks lets the problem resolve on its own. If this is not possible, using an electric razor or single-bladed razor may allow for a less close shave, keeping the pseudofolliculitis barbae under control. Softening the beard with a wet, hot washcloth or shaving while showering in hot water also helps control the condition.
As Wikipedia points out, pseudofolliculitis barbae, also known as barber's itch or razor bumps, is the medical term for persistent irritation that results from shaving. It is most likely to occur with curly hair. When the hair grows back after shaving, it curls and grows into the skin, leading to inflammation. Pseudofolliculitis barbae causes the skin to look red or even pimply. If the area becomes infected, inflamed pustules can form, and keloid scarring can occur in the beard area if the condition is left untreated.
