- APlace a processing cap over the rods
- BRinse the hair thoroughly with water
- CApply neutralizing solution
- DApply a pre-wrap lotion
Show answer & explanationAnswer & explanation
Correct answer: A. Place a processing cap over the rods
Placing a processing cap over the perm rods helps to trap heat and create a controlled environment, which is essential for the chemical solution to penetrate the hair and process effectively, leading to proper curl formation.
Why the other options are wrong
- B. Rinsing the hair is done after the waving lotion has fully processed, not before.
- C. Neutralizing solution is applied after the waving lotion has processed and been rinsed out.
- D. A pre-wrap lotion is applied before wrapping the hair, not after.
Perm Processing Environment
Creating the optimal conditions (e.g., using a processing cap and sometimes heat) to ensure the permanent waving solution effectively breaks and reforms the hair's disulfide bonds.
- Processing cap traps heat and moisture
- Consistent temperature aids chemical action
- Ensures even and effective curl formation
Memory trick: Wrap, Cap, Wave, Rinse, Neutralize, Condition - that's how you permitize!
