Why should color or lightener be applied carefully and not left to process beyond directions?

Correct answer

Over-processing, especially with lighteners, can seriously damage or break the hair

A It saves money
B Color never damages hair
C Longer always looks better
D Over-processing, especially with lighteners, can seriously damage or break the hair

Why this is the answer

Color, and especially lightener (bleach), must be applied carefully and processed only for the time the manufacturer and strand testing indicate, because over-processing — particularly with strong lighteners — can seriously dry out, weaken, and break the hair. Lightening is one of the more damaging services when done carelessly. Monitoring, strand testing, and respecting timing protect the hair's integrity. The principle that more processing is not better, and that lighteners demand particular caution, is reinforced in the coloring content of the exam.
