Shaving regularly does not actually make hair grow back thicker or faster in men. When you shave, you are cutting the hair at the surface level, which gives it a blunt edge as it grows back. This may create an illusion of thicker hair growth, but in reality, shaving has no impact on the thickness or rate of hair growth.
However, frequent shaving can sometimes lead to skin irritation and ingrown hairs, especially if not done properly. It is important to use sharp razors and proper shaving techniques to minimize these issues. Ultimately, the effects of shaving on hair growth primarily involve cosmetic changes rather than actual alterations to the hair follicles themselves.
