Abstract:
1. A method for styling hair, comprising: applying a light-absorbing composition to protruding hair fibers of an individual; generating a predetermined number of pulses of light each having a predetermined electromagnetic spectrum with one or more wavelengths absorbable by said light-absorbing composition; directing said pulses of light at least in part towards portions of said protruding hair fibers to which said light absorbing composition has been applied, said pulses having at least one pulse duration and a total energy all predetermined to differentially heat the hair fibers in a region along one side of the hair fibers and thereby effectively vary curvature of the hair fibers in said region owing to absorption of light of said pulses by at least said light-absorbing composition; and by virtue of the directing of said pulses of light towards said protruding hair fibers and absorption of light of said pulses by said light-absorbing composition, changing curvature of said hair fibers in said region, without removing more than an incidental number of the hair fibers.
