The hole. This is perhaps the most difficult split end to find. The hair shaft has developed a split in the middle of the shaft, but the top and bottom of the hair is not split. To find this one, look for a small section of hair that reflects light differently to the rest of the shaft - it seems shinier. When you take the hair above and below this shiny segment and push them together, it pushes the split apart and creates a hole.
