Comparing RevAir directly with traditional blow dryers can be difficult. RevAir and a blow dryer both use heated air to dry and style hair. That is where the similarities end. RevAir consists of a vacuum motor and a heater that injects a small amount of heated air into the incoming air stream. RevAir gently draws the moisture out of the hair using suction and very little heat to inject a small amount of warm air into the air stream. Frizz is eliminated naturally because the air stream is flowing in the same natural direction as the cuticles, sealing them and locking out frizz. The drying efficiency is at least 3X that of a traditional blow dryer.
