Razor bumps are also known as pseudofolliculitis barbae, and they are small bumps caused by irritation, according to WebMD. The bumps actually result from hair curling back onto itself and then growing into the skin after shaving.

Razor bumps can cause pimples and may even result in scar formation. Although avoiding shaving the back of the neck can put an end to razor bumps in that area, those afflicted can also use clean needles to release the hair shaft that has become embedded. Another option is to use depilatories on the area instead, although these types of hair removal products can also cause irritation. Shaving bumps and razor bumps can be reduced by showering in hot water prior to shaving, which softens the hair and opens up the pores. The use of an electric razor and thick shaving gel can also help thwart the bumps.
