ok I have cornrows in my hair right now (I want to try and do this for the whole summer).I am going to try and keep them for 2weeks @ a time. I have only had them in for a week now and I am going crazy because I dont think I am washing my hair right. Can someone please tell me how many times week I should wash my hair, how to wash without messing them up, but getting my scalp clean.how to moisturize my hair, and how many times I should moisturize them. thanks alot. oh and will my hair grow even if I add extentions to the cornrows?
