Coppola Keratin Complex Natural Keratin Smoothing Treatment for Blonde and/or Highlighted hair is specifically formulated as a revitalizing and rejuvenating Keratin treatment that eliminates frizz and curls (similar to the Brazilian Treatment). The advanced patent-pending formulation straightens and smooths hair by infusing the highest quality of natural keratin deep into the damaged cuticle eliminating up to 95% of the frizz and curl. The keratin treatment therapy encases the hair follicle with a keratinous bond to promote healing and helps keep environmental toxins, such as smoke, pollution and ultraviolet rays, from entering the hair. Typical results last 3 -5 months. It can be used on Color and Chemically treated hair.
