Shampoo help!!!! Growing out of L'oreal Kids?

I have been using L'oreal Kids, for almost all my life. I am currently 12 but turning 13 in about 10 months. I have straight soft hair. I want to use something different than L'oreal Kids because well I think I'm growing out of it. And I'm heading into high school next year. Can you reccommend a product that helps keep natural healthy hair? Thanks! PS I don't wnat something too strong! Thanks a bunch! Include websites if you can pleasee ! =D
