puberty.....
Actually, boys' hair can grow just as long as girls' hair. How long your hair grows only depends on how short you cut it.

They go through puberty
Boys and girls both have the same head of hair but girls tend to grow their hair longer rather than boys who cut it short. :)
Both girls and boys grow hair!!
