Hydrolyzed soy protein for fine thin hair plus panthenol. Both super star ingredients to treat broken, dry, or damaged hair. I use this daily on my mids and ends and my hair has never felt better. No other Dove formula does that for me. Plus this is PETA certified and that's a big deal for me since I stopped using products that were tested on animals. Liter size bottle with a pump at this price point is good but the fact that this transformed my hair makes it 5 stars. I used to be salon only products until I learned that it's not the name on the label that good for your hair it is the ingredients inside the bottle. I am 51 and this is best my hair has felt in almost 5 years. This formulation is only available at Sam's Club that I could see. I have compared the ingredient list to all other Dove conditioners and none of them match the ingredients in this formula. If your hair is rough, damaged, dry, or broken get this. It fixed my hair texture, and my hair doesn't tangle anymore. Drugstore Dove knocks it out of the park. Worth the price of membership just to get this.
