About this product

Apply to clean, towel-dried hair, leave on for at least four minutes, and continue with styling — no rinsing required. The transformative results include restored strength, softness, elasticity, and shine, especially in heat-damaged, chemically-processed, or bleached hair. Effective on every hair type. Use biweekly for ongoing repair, more frequently after major chemical services. Celebrity stylist favorite for set days.
