I got Tresemme keratin smooth shampoo a while ago.
I find no difficulty in using this shampoo, It will produce good amount of foam. It will remove all greasiness from your hair. You will find oil free and dust free hair after using this shampoo.
The concentration of this shampoo is very high which results in acid like feel on you scalp and results in rough and brittle hair.
Fragrance of shampoo is not bad.
Overall my experience with tresemme keratin smooth shampoo is not really good. A big no to this shampoo.
