Razor burn refers to a rash or bumps caused by shaving dry skin, not using enough cream or gel, or shaving too hard, too fast or too close. Shaving does not simply remove hair. It also removes skin cells. Hair may also be cut off slightly below the skin's surface, especially if you shave against the direction it's growing so that the razor catches and pulls it away from the surface. Shaving too hard or too close causes tiny cuts or openings that allow bacteria to enter. When skin grows over the open hair shaft, the hair cannot grow up and out and instead grows down into the follicle. Hair that is naturally curly may kink around and grow into the skin above or below the surface. All of these can cause inflammation and a buildup of dead white cells and bacteria. The skin may be itchy or red and small bumps may form. These can look like pimples, especially if the follicle becomes infected.
