It's important to keep in mind that even if a wig is labeled as heat-friendly, you should still take precautions when styling it with thermal/heat styling tools. Keep the temperature of your tools between 275° F to 300° F. Too hot and your fiber can become damaged or deteriorate faster, too cool and your fiber will not style. We recommend letting the hair fiber cool in the shape you desire which ensures it will hold the style after it cools. It's also important to use a detangling spray and a wide tooth comb to detangle and help prevent frizzing with synthetic fibers. Frizzing is inevitable and is caused by friction and tension, so be sure to smooth out any frizz using a flat iron, and focus on the nape of your wig where frizz tends to appear quickest.
