How do you make hair grow faster?

stop using hair straightners ect. and let your hair dry naturally as often as you can. Ive found that to be the number one main way to help my hair grown longer and get thicker. honestly. only in the past 2 months since ive almost stopped using hair straightners my hair has grown LOADS! also vitimin b12 is supposed to ehelp so make sure youre getting enough of that
