The apparatus for bleaching hair has a light comb with a comb back, a plurality of comb teeth extending from the comb back, a device for guiding light from a light source through the comb back into the comb teeth, and a device for radiating the light from the comb teeth and parallel to the comb back, this radiating device receiving the light from the light guiding device.

Apparatus for bleaching hair under the influence of light

Process for bleaching hair under the influence of light

A method of treating the surface of an optical structure which comprises forming on the surface a thin layer of organic polymer using a solvent casting technique. Preferably the process includes the subsequent treatment of the polymer layer with a solution of a specific ligand. Complex formation between the bound ligand and its specific binding partner present in a sample to be analyzed alters the optical properties of the diffraction grating surface and the change can form the basis of an assay method.
