The most 10 myths about the human body
1-Body hair grows more when we shave:
Pediatrician Rachel Freeman and assistant professor of pediatrics, Aaron Carroll, authenticated that this is just a rumor, as recent studies have revealed that shaving does not affect the density or percentage of hair growth, in addition to that it removes the external dead part of the hair and not the living internal part that is under the skin.
It never affects the percentage and type of growth. Shaved hair is usually coarse, which leads you to believe that it is thicker.
