Curl Nourishing Shampoo (CNS) is a gentle cleanser fortified with Hydrolyzed Quinoa Protein Seaweed Extracts specifically designed to nourish and strengthen curls. CNS has a low pH of 5.2 helping to close the cuticle, define the curls and add shine. Kukui Seed Oil adds moisture to the hair, smoothes rough cuticle and calms frizz. Fennel Seed and Sunflower Seed Extracts kill any excess ammonia peroxide left over after color services; extending the vibrancy of all hair colors. The vegetable based sun filters in CNS shield against fading while adding moisture for radiant healthy looking curls.
