The name describes a condition where several separate hair fibers bunch together and emerge from the skin through a single hair canal. Pathology shows that deep in the skin several dermal papilla are closely situated with each producing a fiber, but these separate hair follicle bulbs combine together into one hair canal towards the skin surface. Folliculitis can sometimes be associated with this condition.
