Matrix SoColor Pre-Bonded Ultra Blonde is the high-lift side of the SoColor permanent line: lift and tone in one step for up to 5 levels of lift, with a built-in bonder that helps protect the hair fiber while it lightens. Low-ammonia formula leaves hair conditioned with a clean, polished blonde tone.
Choosing a shade: UL-AA is designed for levels 5 and 6. UL-A+, UL-V+, UL-N+, UL-P and UL-N are designed for levels 6 to 8. The + shades give the highest lift.
Mix 1 part Ultra Blonde with 2 parts 30 or 40 Volume Matrix Cream Developer and process 50 minutes. The texture and porosity of the hair will affect your ability to achieve cool blonde results. Not recommended for gray coverage.
