Show answer & explanationAnswer & explanation
Correct answer: A. Blot excess water from the hair with towels.
After rinsing the waving solution, it is crucial to thoroughly blot excess water from the hair while the rods are still in. This step prevents the neutralizer from being diluted, ensuring proper re-bonding of the disulfide bonds.
Why the other options are wrong
- B. Blow-drying completely dry is incorrect; the hair should remain damp for neutralizer application.
- C. Rods are removed *after* the neutralizer has been applied and processed, not before.
- D. Pre-wrap lotion is applied *before* the waving solution, not after rinsing it out.
