thanks to everyone.
I have type 4a thick relaxed hair with highlights that is just past my shoulders in the back and and little shorter in the front. Right now I shampoo and condition my hair with Aveda every week with either color conserve or sap moss.(I also use kera care) I get a relaxer every six to eight weeks. My hair is pretty healthy. I just want to know what else I can do. I would like to add about 6 to 8 inches to my length.
