Colour Undo Hair Colour Remover, 3 Application Kit

• Three application colour remover kit
• Reverses the permanent colouring process
• Works on artificial pigment, not your natural colour
• Ideal for longer hair or stubborn, built-up colour

Colour Undo works by reversing what a permanent colour does. Permanent colour deposits small artificial pigment molecules inside the hair, and Colour Undo shrinks those molecules back down so they can be rinsed away, which means it targets the artificial colour rather than lifting the hair the way bleach would. This is the three application kit, which is the one to choose for longer or thicker hair where a single application won't cover the whole head, or where colour has built up over repeated applications and needs more than one pass to shift properly.

Key features

• Reverses the permanent hair colouring process
• Shrinks artificial colour molecules so they can be removed
• Targets artificial pigment rather than lifting the hair
• Three applications included
• Ideal for longer hair or heavily built-up colour

How to use

Follow the instructions supplied with the kit carefully, including mixing, application and timing, and rinse thoroughly and for as long as directed, insufficient rinsing is the most common cause of colour reappearing afterwards. Where colour is stubborn, a further application can be carried out following the manufacturer's guidance on timing between treatments. Results vary depending on the colour history of the hair, so a strand test first is always worth the few minutes it takes. Carry out a skin allergy alert test before use as directed by the manufacturer.

Who it's for

This kit is for colourists working on longer hair or heavily coloured hair, and for anyone facing a colour that's built up over years. We've spent years helping clients in Codsall look and feel their best, and as a working salon, we know one application rarely shifts a decade of box dye, having three to hand means you can keep going rather than stopping halfway and rebooking.
