Keep your hair color looking fresh and vibrant for up to 12 weeks with Aveda Color Control Leave-In Treatment: Rich.* This 98% naturally derived** leave-in treatment is formulated for medium to thick hair types. It dramatically reduces color fade for long-lasting vibrancy and color, instantly detangles, softens hair, and leaves color looking radiant. It protects against water fade, the number-one cause of color fade, and heat fade; it works as a heat-protection spray to protect against damage from heat styling up to 450 degrees, which impacts color radiance. Sand ginger, a naturally derived UV filter, protects color-treated hair from drying effects of the sun. Certified organic apricot and avocado oils work together to nourish, smooth, and seal the cuticle, helping to lock in beautiful, radiant color. Formulated without: Animal-Derived Ingredients, Silicones, Gluten, Mineral Oil, SLS, SLES, Synthetic Fragrance, Parabens, Phthalates, Petrolatum, Paraffin, and Formaldehyde Donors. *Ex vivo testing.
