Show answer & explanationAnswer & explanation
Correct answer: A. Rinse the hair thoroughly to remove all lightener.
After lightening, it is crucial to thoroughly rinse all lightener from the hair to stop the chemical process and prevent further damage before toning.
Why the other options are wrong
- B. A protein treatment might be applied after toning, but not directly after lightening and before rinsing.
- C. Shampooing and conditioning might be done after the toner is rinsed, but the immediate step after lightening is rinsing.
- D. Porosity equalization might be considered, but the most immediate and critical step to prevent over-processing is rinsing out the lightener.
