If residual bleach and uneven toning are two of your biggest pain points, Matrix has the perfect product for you. The new Unbreak My Blonde Bleach Finder Color Changing Lightener Rinse changes color on contact with bleach to ensure proper removal every time. This backbar shampoo was designed with pros in mind to locate and remove bleach to avoid sneaky porosity hot-spots and uneven tones.
When applied, if the shampoo stays yellow, all bleach has been properly removed and you're good to tone. If the formula turns pink, that means residual lightener has been detected in the hair and it's time to rinse again.
