Which process method is described as lifting the hair color first and then applying a new shade to reach the final tone?

• A. Single Process
• B. Double-Process
• C. Highlighting
• D. Toning Only

Answer: (B)

Two-step color method, often called double-process, starts by lifting the natural pigment to a lighter level, then applying a new shade to deposit pigment and reach the final tone. Lifting opens the cuticle and breaks down melanin, creating a pale enough base so the chosen color can register true and control brassiness. After achieving the lift, applying the final shade deposits the intended color, producing the desired final result. This approach is used when the target color is lighter than the starting level or when a toner is needed to neutralize unwanted undertones. In contrast, a single-process color deposits pigment in one step without significant prior lifting, highlighting selectively lifts only portions of hair, and toning alone focuses on neutralizing or adjusting tone without substantial lift.
