So you want to avoid any shampoos with SLS it's not good for black hair. Our hair is naturally low porosity - harder for moisture to get in our hair follicles.
Check out Cantu and Giovanni..if not just read the labels and make sure it doesn't list Sodium lauryl sulfate
"Sodium lauryl sulfate is a common ingredient in many shampoos that gives it a thick, foamy lather that seems to ensure TV commercial-clean hair. Although shampoos that contains this lathering agent might clean your hair well, they may also dry your scalp or strip the color from dyed hair".
Also dont shampoo everyday. Do twice a month and then get down to once a month. You can condition everyday and even use a leave in conditioner every time you take a shower. Keep the hair moisturized.
