Osmo Ikon Bleach Seeker - 1000ml

Bleach Seeker – Colour Changing Lightener Rinse is a smart, colour‑indicating shampoo that removes the uncertainty from post‑lightening cleansing. The formula shifts from yellow to pink when it detects lingering lightener particles in the hair , giving you a clear visual cue that additional cleansing is required. By guiding you to fully eliminate residual bleach, it creates a cleaner, more balanced canvas that supports even, predictable colour development every time.
