PHYSICAL METHOD FOR BLEACHING KERATIN FIBERS
The invention relates to a method for bleaching keratin fibers comprising the treatment of fibers with light from a pulsed, non-coherent light source of low or high energy density preferably in the range of 0.5 to 100 J/cm<2>. The preferred light source is a gas discharge light source whose lambda </= 500 nm spectral component is faded out.
