This professional-grade hair masque utilizes a highly nourishing blend of Shea Butter and Silk Proteins (along with boosting amino acids) to target and seal dry hair cuticles. It deeply moisturizes hair lengths to lock out humidity, providing up to 96 hours of continuous frizz control. It also provides an external barrier to protect your hair against environmental elements and heat styling damage, ensuring your strands stay silk-smooth, shiny, and easy to detangle without any breakage.
