In a double-process after rinsing and checking for scalp abrasions you should:

• A. Rinse again and apply conditioner
• B. Mix and apply toner
• C. Apply a gloss treatment
• D. Apply neutralizer only

Answer: (B)

In a double process, the important next step after bleaching and checking the scalp is to neutralize the lifted tones and set the final shade. This is done by mixing a toner with developer and applying it to the hair. Toner deposits just enough color to counteract brassiness (yellow/orange tones) and yields the desired tone, whether ash, beige, or cool-toned hues. It’s the targeted step that finishes the color lift, bringing the hair to the intended result.

Rinsing again and conditioning wouldn’t change the corrected tones, and a gloss treatment, while it can add shine, isn’t the immediate corrective step for brassiness in a double-process. A neutralizer isn’t used here to deposit color; neutralizers are used in other chemical processes, not to finish a color lift.
