This special Trichup Hot Oil Treatment Hair Mask contains unique Keratin which is distinct from other proteins in that it is rich in Cysteine which is responsible for its unique strength and protective qualities. A tough smooth Keratin film coating the hair shaft reduces split ends and improves hair appearance and combability. Keratin protein binds moisture to the hair and improves shine volume and manageability. Increased moisture content of the hair gives increased flexibility and tensile strength. Its exotic delicate fragrance further adds to your crowning glory.
