Designed to be used in conjunction with New Wash—the award-winning detergent-free hair cleanser—Hairstory’s Purple Color Boost keeps blonde, silver and gray tones bright and brass-free, without stripping the hair. This complimentary product utilizes nourishing ingredients and a first-of-its-kind formula that cleans, conditions and tones without harsh foams and damaging detergents found in traditional shampoo. @hairstorystudio
