René Furterer Okara Radiance Enhancing Shampoo is a gentle shampoo that protects and boosts the radiance of colored hair. Made from 100% natural ingredients, this enhancing formula is infused with the powerful properties of okara and witch hazel extract, which restructure and repair damaged hair deep down and reinforce the hydrolipidic film that protects the scalp. This sulfate-free shampoo, especially formulated with an acidic pH of 5.5, preserves the intensity of the color and keeps it from fading, leaving the hair as bright as the day it was colored, infinitely soft and shiny, and wrapped in a delicious floral perfume.
