That pesky condition known as pseudofolliculitis barbae, or PFB, is also known as razor bumps. PFB is caused by the hair as it grows back in after shaving. For people with naturally curly or kinky hair, this condition can be problematic. For men, daily shaving can be painful and have a negative impact on appearance. PFB can make the skin look itchy and red, and in some cases, it can even look like pimples. The follicles can become inflamed and pustules can form especially if the area becomes infected.
