What is the purpose of prelightening hair before applying toner?

• A. To lighten the hair to reach the desired level before tone
• B. To condition the hair
• C. To wash out color completely
• D. To add shine

Answer: (A)

The main idea is that toner deposits color and cannot lift darkness. Prelightening lightens the hair to the appropriate level so the toner can sit on a pale, even base. If the hair isn’t light enough, underlying yellow, orange, or brassy tones will still show through and the toner won’t achieve the intended shade, often resulting in a muddy or off-tone result. By lifting to the target level first, the toner can deposit the correct pigment to neutralize or adjust the tone cleanly, giving you the desired result (for example, a cool ash or a warm beige) consistently across the hair. Prelightening is about achieving that proper base for toner, not conditioning, washing out color completely, or adding shine.
