Developed specifically for dull and lifeless hair, Ashley Joy Revitalizing Hair Mask adheres to the hair very well and creates a multifunctional protective film layer due to the Silk Protein it contains, similar to keratin. It also has a strong water retention capacity - thus it has moisture-storing properties and revitalizes the hair. It repairs hair breakage and damage thanks to the layer it forms on the hair strand. It prevents crusting on the scalp with its moisturizing feature. Biotin, an important vitamin, strengthens the hair and gives it vitality and shine.
