Top Trend Lace HD Wavy 18” by Jon Renau is part of the Heat Defiant Topper Collection. The gentle waves are made with heat friendly synthetic fiber for versatile styling. The double monofilament top helps conceal the front clip and allows you to change the direction of the part. The SmartLace front creates a seamless hairline for a realistic appearance. The machine-wefted back adds more volume. Perfect for mid to progressive hair loss, this hair topper secures with six clips for a comfortable fit and amazing coverage. Pro Tip: After washing your topper, scrunch the hair to refresh its curl pattern.
