Abstract: A headgear lasing system, including: a power supply; a laser device coupled in power receiving relationship to the power supply, and configured for generating laser radiation effective to promote growth of head hair; a multiplicity of optical fibers coupled with the laser device to receive the laser radiation for transmission thereof through the optical fibers to respective end portions thereof; and a support that is configured to overlie a head region, and to which the end portions of the optical fibers are secured so that the laser radiation transmitted through the optical fibers is directed therefrom to the head region. The support may be a separate structural component that is secured to an existing headgear article, or the support may be a constituent part of a headgear article, such as a crown portion of a cap or hat article. The headgear lasing system is usefully employed to impinge lasing radiation on a scalp region of a wearer, to mediate hair growth on such scalp region.
