What may be required if the desired amount of lift is not achieved using a single-process color?

• A. Prelightening
• B. Addition of a temporary color
• C. Addition of a filler
• D. Addition of a demi-permanent color

Answer: (A)

When you want a lighter result than your starting shade, you often need to lift some of the natural pigment first. If a single-process color doesn’t achieve the desired lift, prelightening is used to remove pigment and raise the hair to the level needed before applying the final shade. This creates a more accurate, even result and helps with porosity differences across the hair. After prelightening, you can apply the chosen color or toner to reach the target tone. Temporary color only sits on the surface and won’t lift; demi-permanent color deposits tone without significant lift; a filler helps even out porosity and undertones but doesn’t provide the necessary lightening by itself.
