This invention provides a method for fixing artificial hair for eyelash extensions onto natural eyelashes. In eyelash extensions where multiple artificial hairs are glued to natural eyelashes growing on the eyelid, reliable glue fixation of the artificial hairs is particularly difficult, and most artificial hairs fall out within a shorter timeframe than expected. First, a liquid adhesive with cyanoacrylate as the main component is applied to the root of the artificial hair to be fixed. The same adhesive is then applied to the opposite side of the pre-attachment position on the periphery of the natural eyelashes used to fix the artificial hair. The glue-coated artificial hair is then glued to the pre-fixation position on the natural eyelashes. Next, the same adhesive is applied to the root of the next artificial hair to be fixed, and this artificial hair is glued to the opposite side of the previously glued position. This process is repeated sequentially. As a result, the adhesives attract each other due to the intermolecular forces generated between the adhesives adhering near the roots of the artificial hairs, forming a stable film of adhesive covering the roots of the artificial hairs on the periphery of the natural eyelashes.
