This shampoo claims to contain Red Algae and Keratin nutri complex which are supposed to fortify the structure of damaged hair. After using Dove, Regenerative shampoo for a week I can say that it is a decent shampoo and works OK for me. My only concern is that it contains sulphates and silicones. Hense, this won't make it to my permanent cabinet. As far as it claims are concerned, I did not really notice any reparative or Regenerative effects on my hair. It made my hair soft. My hair felt clean like they would after using any other normal shampoo. I did not experience increased hair fall however it may have different effects on different hair types. Also keep in mind that hair fall does not solely depend on a shampoo it largely depends on your nutritional intake.
