Everyone in the 1970s seemed to own hot rollers, and hopefully you kept yours because they’re back in style. Spritz almost-dry hair with a spray gel. Then separate all of your hair into small, tidy sections. Take a roller and place it on the end of a section of hair and slowly roll the roller and hair up toward your scalp. Secure it with a bobby pin and spray with a light hairspray. When all sections of hair are rolled, let your hair dry completely for about an hour.
