Your daughter is four year old and her hair will not grow what should you do?

It's pretty wierd but sometimes a child's hair doesn't grow for a while and theirs not much you can do but if you are really concerned i would recomment talking to someone that works in a salon and see if they know about anything that might help get a child's hair to grow. i do know some things that will help though. 1. when sampooing and conditioning hair massage head 2. sleep will definetly help i learned that sleeping can actually some how get your hair to grow faster it may sound crazy but it works
