I．緒言

1) Bifurcated Hair

In 1952 three bifurcated hairs, ( 1 white, 1 blonde,1 dark brown) of the scalp of a 27 years old man was found (Fig.1) and another white bifurcated hair was added in 1954 (Fig 2.) which makes a total of four.

These hairs were provisionally named as "bifu-rcated hair" after macroscopic and cross section examination, differentiating these from Tricho-ptilosis.
