I have hair that is thick to the point that it looks like a wig. It’s frustrating because I like messy look styles. Shampoo weighs it down and adds to the problem. I’ve been using this for years after my hairdresser suggested it. I only need a small amount and my hair is so clean, has much more volume, and a surprise to me is no flakes from my scalp! I love this shampoo. It’s hard to find so if it’s being discontinued I have no idea what I will use instead. I use the conditioner as well and the parts of my hair that are curly have the best curls ever with these products.
