DOES SHAVING MAKE HAIR GROW BACK THICKER?
Hair does not grow any faster and does not get any thicker if you shave. As hair grows out, however, the blunt tip of the hair may cause the area to feel coarse or "stubbly" for a short period of time. A hair fiber is made of a protein called keratin. The visible portion of the hair that is cut by shaving has no biological activity. Since this "dead" hair shaft cannot send information about being cut to the hair follicle (the site of hair growth), growth continues as usual.
