If you enjoy styling versatility, human hair or heat-friendly synthetic hair are the way to go. While human hair offers the most natural look and feel plus styling versatility, heat-friendly synthetic hair also allows heat styling (optimal temperature of 250-275 degrees — never go above 350 degrees). Proper care is vital to keeping heat friendly hair looking its best. A wide tooth comb should be used (not a brush) and it is best to avoid combing while wet. Use of product specially designed for synthetic hair, such as BeautiMark, can also help maintain the quality and condition of the hair. We also recommend detangling spray! With proper care, heat-friendly synthetic hair should last up to a few months.LEARN MORE
