What can happen if a neutralizer is left on hair for too long?

Leaving a neutralizer on the hair for too long can lead to dryness, brittleness, and potential damage because neutralizers contain strong chemicals, primarily hydrogen peroxide, which are designed to stabilize the hair's new shape after a perm. These chemicals work to reform the disulfide bonds in the hair, essential for maintaining the desired curl or wave pattern. However, if they remain in contact with the hair for an extended period, they can excessively strip away moisture and weaken the hair structure. This prolonged exposure disrupts the balance that neutralizers are intended to achieve, ultimately compromising the hair's integrity and leading to adverse effects like breakage and frizz. Proper timing and attention during the neutralizing process are critical for achieving healthy, desirable results.
