HEATHER by ENVY features the latest in heat friendly technology with a unique blend of 30% human hair / 70% synthetic that withstands temperatures up to285° Fahrenheit/120° Celsius. Brush, comb or blow day and our exclusive EnvyHair™ will maintain the feel and texture of human hair—while our Mono Top Lace Front construction and hand-tied sides and back provide an equally natural appearance. For a less constructed look, use your favorite styling cream or pomade to add some spiky texture.
