The type of hair dryer that salons use depends on the salon itself. Some salons use a professional-grade hair dryer that costs hundreds of dollars like the BaBylissPRO Nano Titanium Dryer. Other salons may use a less expensive hair dryer that still gets the job done like the Revlon 1875W Infrared Hair Dryer. However, there are some features that are common among salon hair dryers, such as high power and multiple heat and speed settings.
