L'Oréal Professionnel Série Expert Liss Unlimited Shampoo was developed with straight and rebellious hair types in mind. This professional shampoo is the first step to get perfectly straight hair without a flyaway in sight. It will not only gently cleanse and purify the hair and scalp but also help to discipline the hair. The formula has Pro-Keratin, Amino Acids plus wheat protein, which helps to improve and maintain the hydration of the hair. Furthermore, it strengthens the hair structure and makes it soft and shiny. Additionally, Kukui Nut and Primrose oils will protect the hair against both heat and humidity. When used in combination with other L'Oréal Professionnel Série Expert Liss Unlimited products, this shampoo will help to keep the hair disciplined and frizz-free for up to 4 days.
