Two cases of spun glass hair have been investigated with SEM and TEM. The SEM studies confirm previous findings by other authors. The TEM investigations reveal a completely normal cross section appearance. These findings stress the need for investigation of the time sequence of the keratinization process of the different layers of the inner root sheath.
