Different studies have been done on this topic, most of the older studies on the vertical section confirm that peribulbar infiltrate is an important finding, however the newer studies on the horizontal section, mention decreased anagen to telogen ratio, decreased terminal to vellus hair ratio and a decreased follicular count. These studies on horizontal (transverse sections) have shown that transverse sectioning is superior and more diagnostic in studying alopecias. However, these studies are based on multiple cut sections, because in a single cut section, we may miss a few hair bulbs above or below, depending on where the section is taken. Hence this makes it a time consuming, technically challenging and expensive procedure.
