I started using Tresemme Keratin Smooth Shampoo and Conditioner 2 months ago. It is such quality and makes my hair not only look different but feeling different also. The best part is, I don’t even have to use more than one small squeeze to get enough shampoo or conditioner to make my hair feel clean and healthy. In combination with other tresemme products, my hair has never looked and felt better before.
