It is recommended that Crown Hair Building Fibers be applied after the use of any styling tools such as hairdryers, flat irons or curling irons. Styling products (other than hairspray) should be applied to the hair prior to applying Crown Hair Building Fibers. Applying any form of gels, mousses, serums etc. after applying Fibers may cause the Fibers to shift or wear off onto ones hands and could expose the areas that were meant to be covered. Let styling products dry before applying Fibers.
