What is a razor-burn , how can it be prevented ?
Normally a hair is tapered and is very small and fine when first growing through the skin but when you shave it, you slice it at an angle leaving a wide hair with a chisel like edge such that when the hair starts growing past the surface of the skin, the chiseled edge cuts into the skin. Razor burn can be prevented by making two passes while shaving, the first pass bevels the cut in one direction while the second in the other so the chiseled cutting edge is in the middle of the hair and not at one or the other edges hence it doesn’t dig into the skin. The rotary based electric razors are better for avoiding razor burn as moving the heads around cuts he hairs in every direction. A well designed precision made foil on an electric razor helps prevent razor burn and these designs and fabrication techniques are the mark of a really good body groomer razor such as the Seiko Cleancut.
