The divided strands are subjected to a dielectric plasma treatment by drawing an apparatus connected to a high voltage source (8) through the strands. The apparatus can be in the form of tongs or have a comb-like structure. ## Claims ### Claim 1 A hand-held or moveable apparatus for treating human or animal hair, comprising a tongs-like body having two levers with which a divided strand of hair can be grasped and guided between contact faces of the two levers, wherein said contact faces are situated opposite one another, and each of said contact faces is formed by a dielectric that covers a flat electrode, wherein said flat electrode is connectable to a high-voltage source and one of said flat electrodes can be supplied with a voltage that differs from a voltage supplied to another of said flat electrodes. ### Claim 2 (depends on 1) The apparatus as claimed in claim 1, wherein said flat electrodes are embedded in said dielectric. ### Claim 3 A hand-held or moveable apparatus for treating human or animal hair, comprising a comb-like body having tines which run parallel to one another, wherein said tines are formed with a conductive core which is surrounded on all sides by a dielectric, and wherein said conductive cores of said tines are connectable alternately to different voltages of the high-voltage source in order to form a plasma between adjacent tines. ### Claim 4 (depends on 3) The apparatus as claimed in claim 3, wherein the dielectric which surrounds said conductive core is a cohesive integral layer. ### Claim 5 A method for treating human or animal hair, wherein the hair is divided into strands; comprising the steps of subjecting divided strands to dielectric plasma treatment by an apparatus which is connected to a high-voltage source, and drawing the apparatus through the strands, wherein one of said electrodes is supplied with a voltage that differs from a voltage supplied to another of said electrodes. ### Claim 6 (depends on 5) The method as claimed in claim 5, wherein said divided strands are grasped between two flat electrodes which are arranged on contact faces of tongs-like levers of said apparatus to provide one dielectric on each of said contact faces, and said direction through said divided strands. ### Claim 7 (depends on 5) The method as claimed in claim 5, wherein said hair is divided into strands by means of a comb-like structure having tines which run parallel to one another, wherein each of said tines has a conductive core which is surrounded on all sides by a dielectric and said conductive cores form electrodes, and said electrodes are connected to a said high-voltage source. ### Claim 8 (depends on 5) The method of claim 5, wherein said human or animal hair is uncut or living hair. ### Claim 9 (depends on 5) The method of claim 5, wherein said human or animal hair is cut and fixedly arranged on a support.
