Color Wow Dream Cocktails turn blow-drying sessions into luxe treatments by infusing vital natural ingredients into the hair to help improve the overall quality of each strand. These nutrients are activated by heat, and improve the quality and texture of the hair throughout the blow-drying process. Carb Serum uses an infused carb complex to treat fine, thin, flat hair by bonding a weightless outer fattening layer to each hair strand. The result: instantly thicker, plump hair. This leave-in treatment can be layered with Dream Cocktail Kale Serum to treat multiple hair concerns. Always use Kale Serum first, to penetrate the interior bonds.
