I have thin, colored (almost) natural paint, hair; previously used shampoo, which gave me a perfect size - unfortunately, this shampoo is now no longer available. I began to look for another. I chose this one - Dr Mercola (on the composition and volume of the promises .. and the price is encouraging for a good result). As a result, the volume - at C grade; scalp - also at C grade (slightly annoyed). Of the benefits .. Still, even if the hair is not slicked after application and not electrified - and it's good :) Odor mild pleasant .. Jar beautiful .. So, price / performance ratio is not justified, will not take the next time.
