Definition
Pili gemini defines a situation where the papilla's tip of a hair follicle splits during the anagen phase and consequently grows two hair shafts emerging through a single pilary canal. A papilla tip that divides in several tips will produce several hair shafts, a situation named pili multigemini. Pili gemini or multigemini can occur in each type of hair.
