KYLIE by ENVY features a Mono Top and Handtied sides and back that mimic hair’s natural movement and a soft chiffon lining that will make even the most sensitive scalps happy. Our exclusive EnvyHair™ blend of 30% human hair/70% synthetic fiber was developed as a high-tech alternative to human hair products. Its added moisture-control and the ability to withstand temperatures up to 285° Fahrenheit/120° Celsius let you brush, comb and heat-style with total freedom, while still maintaining the feel and texture of human hair.
