The troubles with colour removers/reducersintroduction

Course summary

Colour removers (also known as colour reducers) are one of the most effective yet misunderstood tools in professional hair colouring.

This guide breaks down how they work, when to use them, and why they can often be a safer, more predictable alternative to bleach when transitioning clients from dark or box colours to lighter or different shades. Unlike bleach, colour removers target only artificial pigment, leaving the natural hair colour untouched and helping achieve reliable results with less damage.Through real client scenarios, the document explores practical applications, common challenges, and troubleshooting techniques, including issues like re-darkening, brassiness, green tones, and compromised hair condition. It also introduces key colour correction concepts such as toning, underlying pigments, formulation after removal, and when a colour remover should be chosen over bleach. Overall, the focus is on building confidence, improving results, and expanding high-value colour services through better understanding and education.
