The Dena by Envy is made from our exclusive Envyhair— a blend of 30% human hair and 70% heat-friendly fiber which can be curled, straightened and blow-dried to create for a multitude of desired styles. Piecey, jaw-length layers perfectly frame the face, while brow-skimming bangs highlight the eyes. And Dena's Mono Top construction with hand-tied sides and back allows a flawless left, right, or middle part.
