To recap, what is the ratio of bleach to developer? It’s constantly 2 to 1, no matter what developer you are utilizing. Do make certain to use a good top quality bleach and also a 20 to 30 volume developer, unmuch less you are skilled in coloring hair.

A 20 volume developer need to be sufficient for functioning on regrowth as it have the right to lift hair up to 2 levels, while a 30 volume developer is ideal for the entire hair size. The bleach should ideally lift your hair to a pale yellow. If you check out any orange or brassiness, you should reuse bleach.

To prevent this from happening in the first place, but, make certain your bleach mixture has the right consistency, and use it initially on the darkest and brassiest parts of your hair.
