Formulated to take out yellow, brassy tones. Ideal for blondes that like cooler tones in their hair. Think of it as your purple shampoo, but way better. *Disclaimer: Due to the ashy, cooler tone in N.01, results can sometimes appear darker depending on the length of time left on the hair. If you consider yourself a bright blonde, we suggest leaving this gloss on for ~7 minutes from the time you start applying to the time you rinse out. To alleviate any of that guess-work, we have now introduced a feature on the site that enables customers to book a free consultation with one of our colorists to go over any questions or concerns that one might have about glossing. Head over to our homepage to schedule your session!
