Chemical straightening increases the porosity of the hair fiber, making it more susceptible to breakage and frizz. This mask acts on distinct layers of the hair strand: Hydrolyzed Keratin penetrates the cortex and fills in microporosities, restoring tensile strength; Argan Oil seals open cuticles, contributing to shine; and Macadamia Oil softens the external surface, prolonging the satin effect. The formula contains no ingredients that alter disulfide bonds, making it compatible with professional straightening.
For very dry, brittle hair or hair with old straightening, application for 20 minutes with a warm towel intensifies the penetration of the active ingredients and deepens the reconstructing action.
