How long will it take to change the bangs back to their original state?

After bangs are soft, it usually takes 3~6 months to recover. Softening is much more natural than ion perming. Don't wash your hair for 2 ~ 3 days after softening, and don't pull your hair hard after softening, which will damage your hair quality and effect.

Wash your hair more at ordinary times, which is conducive to recovery. If it is easy to soften and damage the hair, it should not be more than twice a year. Take good care of your hair, use mild shampoo and better conditioner.
