Can I personally make something for my hair to grow longer?
As far as I know there isn't really a way to MAKE your hair grow. But one way to make it longer is to take care of it now! there are conditioners and shampoos made to help strengthen longer hair. preventing split ends and break offs will help you keep the length you have. things like letting hair air dry, not over dying it, and not brushing it wet will help keep your hair attached so it has a chance to grow.
try brading your hair everynight brfore you go to bed , and it grows 1/2 inch EVERY night ! that is also why the indians braided their hair all of the time
From what I've read, hair will only grow an average of 1/2 inch per month regardless...Take care !!
if you condition your hair it will speed up the process
