To use Wella Color Charm Liquid Hair Color, you will need to first mix the hair color with a developer. Start by mixing 1 part of the hair color with 2 parts of the developer in a plastic bowl. Once you have mixed the color and developer together, apply the mixture to your hair using a color brush. Make sure to saturate the hair thoroughly and work the color through your hair from root to tip. Leave the color on for the recommended processing time, usually between 20-40 minutes. Once the processing time is up, rinse out the color with warm water, and then shampoo and condition your hair.
