I recently cut my hair and it's shorter than the lady was supposed to cut it. another lady said biotin will cause my hair to grow longer. how long will that take? school is starting in about a month and i don't want to go back with the short hair

Worried about hair?: School is one of the most important aspects of a person's life. Her hair... well, that cannot be a big deal. That does not mean hair is not a big deal; it means hair length CANNOT be a big deal. It is mind over body. Hair length only becomes a big deal if one's brain fails to ignore all worries related to length. Biotin will make no difference. A student's hair can grow fine with no supplements.
