Colorants and Developers
Your hair color box always contains two key ingredients: a colorant (usually labeled step 1) and a developer (step 2). When mixed together, the developer works as an oxidizing agent and activates the color. By reacting to the developer, color can penetrate the hair’s inner layer and easily bind to each individual hair. That’s the secret to gorgeous color! It usually takes between 20-30 minutes for oxidization to complete, so never skimp on processing time.
