Is it true that if you put your hair up it will grow long?

i don't believe that put it up will make it grow but try dr.miracle hair products will will grow or try dr.wonder it will grow. I used dr.wonder and it worked it mad my hair grow fast and it's easy it will stimulate your hair you will know when it is working cuz when it tingles. it really helped me grow more hair.then you might want to put in some weave not scalt braids that will pull out your hair but something that's loose and not a scalt thing in your head.just keeeeeep using that brands i talked about it will work if you put a bunit on it after you do it .it will stimulate you hair folcals.oooookkkkk. it will work if you do what i said.
