What Volume Developer Should I Use for Dark Hair?
How Do I Use a 40 Volume Developer to Lighten Hair?
If you want to bleach your own hair, dividing it into several sections will be really helpful to your work.
Step 1
Preparing your bleach is a step. One part powder to two parts developer should be the proportions.
Step 2
Apply color to hair. Begin at the back of the head. In this area, your hair is darker, and it will take a longer period of time to lighten it.
Step 3
Using the 40 volume developer straight on your scalp is not suggested. Because such a strong developer has the potential to burn your scalp, avoiding it is the best way to proceed.
Step 4
Once the 40 volume developer has become the desired shade, it is time to rinse it off.
Step 5
– Please don't bleach your hair more than once in a row.– You should wait a few days before repeating this procedure.– Before using 40 vol on your hair, think it over many times.
