While RevAir is designed as a hair dryer, you can still “dry Rev” to freshen up your hair in between washes. Either use RevAir on totally dry sections for a few seconds (far less time than if you were drying). Or lightly spray your hair with water and Rev till dry. Dry Reving works best on hair that’s been previously dried using a RevAir and will help restore smoothness and shine on those days when you get caught in the rain, or the humidity is simply off the charts!
