All purpose bleach kit with built-in anti-breakage technology to help reduce damage during the lightening process. Pulls out natural colour pigments quickly and evenly for a perfect blonde base.












Your choice of bleach kit depends on your hair and desired lift and colour. The best way to check the colour your hair will go and how it'll feel after using is with a strand test. Check out our bleach, tone and color guides here
