Bleach Seeker - Colour Changing Lightener Rinse is an innovative, colour-indicating shampoo designed to eliminate the guesswork from post-lightening cleansing. Its advanced formula changes from yellow to pink when it detects residual lightener particles in the hair, providing a clear, real-time indication that additional cleansing is required. This intelligent colour-changing technology helps ensure lightener is thoroughly removed, giving you confidence that the hair is clean and ready for the next stage of the service. The result? A cleaner, more balanced foundation that helps ensure even, predictable colour results every time. No guesswork. No compromise. Just precision. How It Works: Detects leftover lightener particles in the hair Changes colour (yellow → pink) when residue is present Guides you to continue cleansing until the hair is fully clean Helps prevent unwanted chemical interference with toners Ensures a more even, predictable colour result How To Use: Rinse hair after lightener has processed. Apply Bleach Seeker and emulsify for up to 3 minutes. Formula will turn from yellow to pink if lightener particles are found. Continue to emulsify until formula remains yellow with no pink in sight. All Yellow? Ready to rinse and tone. Still Pink? Shampoo again. Key Benefits: Smart Colour Indicator Technology - Changes from yellow to pink to signal the presence of leftover lightener.
