[1]: 768 [2] Pili bifurcati is defined by uneven bifurcation of the hair shaft.
[4] The etiology of pili bifurcati is a temporary duplication of the papilla tip that occurs during the anagen phase.
This temporary production results in two full shafts that emerge from a single pilary canal within the same follicular matrix.
Patients with protein deficits can have hypopigmentation and telogen effluvium.
Hair shafts studied under light microscopy reveals the distinctive bifurcations.
