From my experience which has been extensive since I deal with 70% of my clients having eczema, psoriasis or mild cases of dandruff, Aestelance makes hands down the best shampoo for dandruff. The shampoo is called FI (flakey and irritated). Its a liquid based shampoo, so instead of using a cream there is a spout that you press directly on the scalp. This allows a much easier and more efficient way of getting the nutrients directly on the scalp. After application massage into the scalp, rinse, then condition. Make sure to condition with Mud Mask (also made by Aestelance) as it's also very nurturing for the dry scalp. This should clear the problem right up and if it's a bad case you'll need to do one more step. After you shampoo and condition some people need to use a product called Balance ( also by Aestelance). The hair should be towel dried. Just apply balance using the spout directly on the scalp all over, rub it in and don't wash it out. Hopefully this helps!
