Overlapping lightener during a retouch service could:

• A. Cause Breakage
• B. Improve Color Lift
• C. Create Frizz-Free Results
• D. Reduce Processing Time

Answer: (A)

Overlapping lightener on hair that has already been lightened weakens the hair further. Lightener lifts pigment by opening the cuticle and breaking some of the internal bonds in the cortex. When you reapply lightener to the same strand, especially in the areas that are already lightened, the chemical exposure hits hair that is porous and damaged, increasing the risk of breakage, thinning, or even snapping during processing, washing, or styling. To avoid this, you typically apply lightener only to the new growth and prevent it from overlapping onto the previously treated lengths. The other ideas—greater lift, frizz-free results, or shorter processing time—don’t come from overlap and, in fact, overlap tends to create more damage and uneven results.
