Matrix Total Results Unbreak My Blonde Bleach Finder Color Changing Lightener Rinse 1L

The color-changing formula changes color when exposed to remaining bleach in the hair.  The smart cleansing formula works by attaching to leftover bleach particles in the hair after rinsing out a lightener application, balayage or foils - making this the perfect Stylist tool to deliver the best blonde possible, every time! Look out for pink... if you see it, rinse it down the sink!

Benefits:
-  More beautiful even blonde when you ensure lightener is removed properly - especially useful for hard-to-see areas like the nape of the neck!
-  Color-changing formula turns pink when exposed to lightener particles
-  Balances pH of the hair after lightening service, offering a better canvas to tone

How to use:  Keep it on your salon backbar and use as a post-lightener wash service in the salon (pre-toner).
