My hair is really damaged. Will it help to leave in a conditioner longer than the directions indicate?

Conditioners take a certain amount of time to penetrate the hair. After that time, there is no added benefit. Leaving a protein treatment on your hair longer than directed can actually dry hair out even more! However, using heat in conjunction with many deep conditioners will produce a beneficial effect.
