IGNITE by Jon Renau is a Heat Defiant Lace-Front style at a very affordable price, by Jon Renau. The angled layers can be flipped out with a flat iron for a sassy shag or blow-dried over a round brush for a super sleek bob. The SmartLace cap creates a beautiful, natural hairline. Combines the easy wear of a synthetic with flexible styling and feel of human hair with new ultra fine denier fibers. Heat Defiant synthetic fibers withstand up to 350 degrees; blow dry, flat iron, crimp and curl just like natural human hair. Super popular heat-defiant style.
