Add some flair with face-framing feathered layers, a wispy nape and full, airy bangs. Using Tony of Beverly's heat resistant Ambient Fiber. *Designed to withstand heat up to 350 degrees. You can easily achieve different looks using a temperature controlled (240-350 degrees) flat iron or curling iron. After using your iron to straighten or curl, allow fiber to cool for 60 seconds to set style before combing through fiber. The style stays locked in place until heat-styled again. Please check the settings on your heating appliance before applying heat to the fiber. We recommend heat-styling off of the head for safety.
