I have used this for years as I have curly hair and only wash it 1-4 times a week. This shampoo is excellent as cleaning the build up off of my scalp. It is a bit drying as I have elbow length curly, fine hair but a lot of it. I try to use it no more than twice a week and I will sometimes use a gentler shampoo on my ends. My husband has starting using this because I told him it would fix his dandruff and he could stop using the chemicals in the other traditional dandruff brands. Within a couple weeks he no longer had dandruff. He has been using the product now for about 2 years and is very happy with it. He insists that we have it anytime we travel and will never switch brands. This is an excellent, effective and eco friendly product. We highly recommend it!
