No, it lifts your natural hair color by use of the developer. The higher the volume of the developer the more lift you will get in your hair.
When used alone, developer will do nothing to the hair. It is made to be mixed with a hair color.
For 1 part hair color and 2 parts developer, you should mix them in a 1:2 ratio. This means using twice as much developer as hair color. Ensure you measure accurately and mix well for best results in coloring your hair.
