Apparatus and method of hair depilation for destroying follicle cells is provided where an invasive element, such as a waveguide, probe or needle, is inserted into a hair follicle and pulsed laser energy is radially transmitted through the invasive element to the entire lining of the follicle. The blood vessels of the papilla, the hair shaft, the hair bulge and hair bulb are substantially damaged. The laser employed may be at a wavelength that does not penetrate skin. The laser may pulse laser energy through a frosted tip of a waveguide or probe that scatters the laser radiation radially along a length of the frosted tip to the follicle lining. Otherwise, a protective substances, such as energy absorbing particles, may be used to absorb energy and transmit it to the follicle lining such that there is no damage to the outlying skin. Alternatively, a waveguide may be placed in a needle and the needle inserted into a hair follicle. The energy provided by the waveguide is conducted by the needle and radially transmitted to the follicle lining. By the use of a needle, either a frosted fiber or a flat fiber which provides laser energy forward from its tip in a conical shape may be used. |
