I had a few flakes so decided to buy Head and Shoulders.
I have oily hair, but after one month of Head and Shoulders my hair was brittle and breaking off. It also caused sores on my scalp. I would say that I had an allergic reaction to something in the shampoo. I tossed the remainder of the shampoo in the trash, and went back to my light and breezy Sauve.
So if you have any allergies, watch changing shampoos. My head itches just thinking of Head and Shoulders..
