Does shaving make your hair grow back thicker?
Scientists at Gillette have conducted extensive testing on the effects shaving has on both male and female hair growth, texture and colour. This testing has proven that shaving does not affect hair growth, texture or colour. Shaving does, however, alter the tip shape of the regrown hair, which may initially change the way hair feels as it grows back. But if hair is left to regrow completely, it will return to its former state.

In what direction should I shave to achieve the best shave?
Men's facial hair tends to grow in different directions. Start by shaving with light, gentle strokes with the grain. Then, if necessary, go against the grain for an even closer shave.
