From all the bottles collecting under my sink, I can promise you I have tried EVERY brand of clarifying shampoo on the market. I have tried everything from the cheap dollar store stuff to the most expensive salon stuff. NOTHING has worked as well as this does. It cleans all the daily styling gunk from my hair, but it never "strips" it. My hair is never left feeling dry. It actually feels better conditioned after I use this, and I don't even use a conditioner with it. I don't know if it is the baking soda in this shampoo or what it is, but this shampoo leaves my hair with a "slick" feel. It doesn't leave behind a "coating" either. My hair is left shiny but clean at the same time. I have very fine hair that has been thinning from a medication that I have to take. It seems like this shampoo has slowed the thinning because I think it is removing the residual medication from my scalp. For a clarifying shampoo, this doesn't even strip my semi-permanent color either. Most clarifying shampoos will strip it right out. Previous to this, the only two clarifying shampoos that I was satisfied with were Ojon Full Detox shampoo and AG Hair Therapy Renew Clarifying shampoo. I liked those also, but since trying Abba, I'm not going back. This shampoo is just in a league of its own. I hope they never stop making this.
