Number Three Co., Ltd. Proaction For C Salon Exclusive Smooths hair damaged by hair color. Set of 2 Product Description [Shampoo] This shampoo has a buffering effect that neutralizes alkaline components, which can remain after coloring or perming and cause hair damage, returning the hair to its natural, slightly acidic state. [Treatment] This treatment protects delicate hair after hair coloring from fading and damage. I especially like the smooth feeling after using the treatment, and I'm a repeat customer. Using this for a week after hair coloring makes a difference in how long the color lasts. ⚠︎ Please refrain from selling individual items or further price reductions.
