i have seen and heard about shampoo that you use that will make your hair grow faster. has anyone ever used it? does it work? what kind do you reccomend? i am trying to grow my hair out before school starts on august 27th.

I seriously doubt this will work. These have been around for a long time and they have never worked.
I understand that your hair grows faster in the summer.
Your hair will grow faster if you get regular trims, get rid of the split ends. You should make sure your hair is hydrated, conditioned. I don't think dry hair grows as quickly. Don't overwash your hair. It is suggested every other day is better than every day.
