Usually occurring on males of Irish descent. It is a full facially grown beard, with hairs clipped to a length of no longer than 1/2". For a beard be considered a "leslie beard" it's color must be red/reddish/ruddy and the color of the male's head-hair must be of some other shade. The two shades/hue cannot match completely, thus creating a two-tone effect that is irresistible to the ladies.
