A pink hair dryer is a device used to dry hair quickly using a heating element and a fan to blow hot air. Examples include the Revlon One-Step Volumizer Original 1.0 Hair Dryer and Hot Air Brush and the Drybar Buttercup Blow Dryer.
Pink hair dryers are popular because they dry hair quickly and can add volume and shine. Historically, hair dryers were large and heavy, but they have become smaller and more portable over time.
