Using a razor with too many blades can be irritating to the skin; the space between multiple blades is too tiny to cut all the hairs in one pass over the skin, forcing users of multi-blade razors to shave over the same spot many times. The blades also end up cutting the hair beneath the surface of the skin, so while these razors do technically give the user a closer shave, they are also more likely to give the user ingrown hairs.
