Successful Color Treatment

A: To ensure a successful, even hair color process you always need to start with clean, dried hair.
You also want to make sure the hair is in its best possible condition before a color service. This means that you'll want to make sure to condition your hair well before performing a color application. This will ensure that the hair has a good balance of moisture throughout the hair shaft, and that the color formula will absorb evenly, further helping to guarantee even color.
