In a lightener retouch, what may cause hair breakage?

The lightener overlaps
Using a low-volume developer
Not leaving the lightener on long enough
Rinsing the lightener out too soon

The correct answer is: The lightener overlaps

Overlapping lightener means that multiple sections of hair have been coated with the product, often resulting in increased exposure and processing time. This can lead to hair breakage as the lightener can become more concentrated and damaging to the hair. While using a low-volume developer may minimize damage, it may also prolong the lightening process, increasing the risk of breakage due to repeated exposure. Similarly, not leaving the lightener on long enough can result in uneven lightening, leading to the need for additional applications, which can cause damage. Finally, rinsing the lightener out too soon can result in incomplete lightening, leading to the need for another application which can damage the hair further.
