I seriously do not advise you to put henna in your hair. You cant do anything with it after henna treatment as many colors cannot cover it or may turn it weird colors.

If your hair is curly and damaged, you may be surprised to hear that you shouldnt use shampoo. Check out this site

It took me a while to get off the idea of shampoo but you will be amazed at how beautiful your curls can be. ____________________________________________________
