L'Oréal Professionnel Série Expert Inforcer Shampoo gently and effectively cleanses that hair while providing strengthening and repairing benefits. More specifically, this shampoo tackles breakage and split ends while making the hair shinier and softer. Its powerful formula with Biotin and vitamin B6 works deep in the hair fiber to diminish both breakage and split ends. The first helps to restore the thickness of the hair fiber to help to make it stronger and more resilient. Similarly, vitamin B6 encourages the production of keratin to improve the appearance, elasticity, and manageability of the hair. Finally, this shampoo is particularly beneficial for those with thin and fragile hair as it immediately reinforces each strand to reduce breakage.
