Don't be fooled. Contrary to what we usually think, cutting your hair frequently does not make it grow stronger or thicker . Since 1928, several clinical trials have shown that shaving hair does not affect its growth. According to dermatologists, the only thing that happens is that as the hair root is darker and stronger, when removing the ends, for example after a shave, it gives us the false feeling that it is thicker.
Neither are those who warn that by plucking one gray hair we will get seven new ones . What is certain is that situations of intense stress and "penalties" cause the amount of white or gray hair to increase, according to various scientific studies.
On the other hand, neither hair nor nails grow after death . According to dermatologists, this false belief is explained because dehydration of a deceased's body can cause the skin to retract, creating the optical illusion that tissues such as hair or nails are enlarging.
