How long should I dry a roller set under a conventional hair dryer?

Depending on the length of your hair, a roller set should dry in twenty to forty-five minutes under a hard hat or soft bonnet dryer. It is always safest to dry hair on a lower setting for a longer period than to use a high setting for a short time. The setting should never be so high that you are uncomfortable or your scalp burns. Switch to a cool setting for the last five minutes.
