We recommend to set your tool at 120C/250F, as anything higher runs the risk of damaging the hair. The reason why we recommend opting for a lower heat setting is because it will prolong the lifespan of your set. While our own hair may be able to handle a high heat setting, our hair is also constantly getting revitalized from the scalp, whereas hair extensions don’t get that sort of nutrition.
