The answer is definitely not. Our colorists use nothing but New Wash in all phases of the color process to spectacular effect.
We strongly recommend bringing your New Wash to your next color appointment. Customers have told us they sometimes feel awkward about bringing their own product, but you are the paying customer and you should feel confident letting your colorist or stylist know what you want used on your hair and scalp.
Encourage your stylist to investigate Hairstory. The more people who take a stand against detergent, the better; The only use we have for shampoo is to strip unwanted color from hair instead of bleaching.
