Every high-lift blonde I’ve ever worked with leaves the hair rough and brassy. The fault, I believe, is in the way they are created. Most high-lift blondes have an ammonia content of 4% and use double amounts of 40-volume This means you have a working volume of 26.66.
I decided to create chromastics high-lift differently.
Chromastics high-lift (XL-Super) has an ammonia content of 3% and uses equal amounts of 40-volume developer. This means you have a working volume of 20.00. The combination of 3% ammonia and a working volume of 20.00 is much less aggressive that an ammonia content of 4% and a working volume of 26.66.
Here are 2 dye outs on virgin white and virgin salt and pepper hair that show the final result.
In each formula the darker starting level is diluted by the XL-Super and more importantly, there is no brassiness and there is complete gray coverage.
