Shaving Hair Makes It Grow Back Thicker — False

A common belief is that shaving hair causes it to grow back thicker, darker, or faster. This is not true.
Shaving only cuts hair at the surface of the skin and does not affect the hair follicle beneath. The blunt edge of newly grown hair may feel coarser, creating the illusion of increased thickness.
Hair growth rate and thickness are determined by genetics and hormones—not shaving.
