Here's why:
* Hair growth is determined by genetics and hormones, not shaving. Shaving only removes the hair at the surface level. The hair follicle, which produces the hair, remains untouched.
* The hair may appear thicker after shaving. This is because the newly grown hair has a blunt end, making it feel coarser and potentially more noticeable than the tapered end of a hair that has not been cut. However, the hair itself is not actually thicker.
* The hair may also appear darker. This is due to the blunt end reflecting light differently, creating the illusion of darker hair.
In summary, shaving does not change the thickness or rate of hair growth. It simply cuts the hair at the surface, giving the illusion of thicker, darker hair.
