What is the primary effect of leaving water in end papers after rinsing on the curl?

• A. It Dilutes the Neutralizer and Weakens the Curl
• B. It Strengthens the Curl
• C. It Has No Effect
• D. It Speeds Up Processing

Answer: (A)

Leaving water in the end papers after rinsing mainly reduces the neutralizer’s strength when it contacts the hair ends. The neutralizer fixes the curl by oxidizing and reforming the disulfide bonds that were opened earlier. If water is trapped in the end papers, it dilutes this solution, lowering its concentration and weakening the chemical reaction at the ends. As a result, fewer bonds are reformed and the curl ends up weaker. It wouldn’t speed up processing or strengthen the curl, and there is indeed an effect on the outcome.
