Yes, you can use heat tools like blow dryers, curling irons and flat irons on lace bases. However, use the lowest heat setting and keep the tool moving to avoid damaging the lace. Allow your lace base to cool completely between uses of heat tools. Limit use of extreme heat which can cause the lace to deteriorate faster. With regular heat styling, you may need to replace your lace base more often, around every 3 to 4 weeks.
