Abstract: 1. A process for treating hair, skin and nails with an agent which is based on a mixture of a component A, which contains a cationic polymer, and a component B, which contains an anionic polymer having a molecular weight of from 500 to 5,000,000, with the cationic and anionic polymer being present in a proportion of from 0.01 to 10% by weight, calculated in relation to the total weight of the agent, characterised in that the agent is applied to the hair, the skin or the nails, with the anionic polymer which is present in component B being selected from polymers which possess structural units which are derived from the following acids, their salts or acid derivatives: (a) sulphonic acid, (b) phosphoric acid, (c) crotonic acid derivatives selected from: - the grafted polymers of vinyl esters and esters of acrylic acid or methacrylic acid, alone or in a mixture, copolymerised with the crotonic acid, grafted onto polyalkylene glycols whose terminal OH groups are optionally etherified or esterified, or grafted onto azotized polyalkylene glycol oxides; - the grafted and crosslinked polymers which are obtained by copolymerising a non-ionic monomer, crotonic acid, polyethylene glycol and a crosslinking agent; - the terpolymers which are derived from: crotonic acid, vinyl acetate, and an allyl or methallyl ether of the formula <IMAGE> in which R' denotes a hydrogen atom or a -CH3 group, R1 denotes a saturated, straight-chain or branched hydrocarbon chain having from 1 to 6 carbon atoms, and R2 denotes either the -CH3 group or the group -CH(CH3)2; - the tetra- and pentapolymers which are obtained by copolymerising: - crotonic acid, - vinyl acetate or vinyl propionate, - an allyl or methallyl ester of the formula 11, - a monomer selected from: - a vinyl ether of the formula <IMAGE> in which R3 denotes an alkyl group, - a vinyl ester having a fatty acid chain of the formula <IMAGE> in which R4 denotes a straight-chain alkyl group having from 7 to 11 carbon atoms, - an allyl or methallyl ester of the formula: <IMAGE> in which R' denotes a hydrogen atom or a methyl group, and R5 denotes an alkyl group; - the terpolymers of vinyl acetate, crotonic acid and vinyl esters of an aliphatic, saturated monocarboxylic acid which is branched in the α position and which contains at least 5 carbon atoms in the carboxyl group; - esters of unsaturated alcohols and saturated short- chain acids, esters of saturated alcohols having a short chain and unsaturated acids, esters of crotonic acid, esters of long-chain acids and unsaturated alcohol, esters of unsaturated acids and a saturated or unsaturated alcohol having from 8 to 18 carbon atoms or a lanolin alcohol, alkyl vinyl ethers, alkyl allyl ethers, alkyl methallyl ethers, alkyl crotyl ethers and the α-olefins; - copolymers of crotonic acid with ethylene, vinylbenzene, vinyl methyl ether and acrylamide, and also water-soluble salts thereof; - the copolymers of vinyl acetate/crotonic acid with acrylic or methacrylic acid esters or an alkyl vinyl ether; - the copolymers of vinyl acetate/crotonic acid and a monomer which is selected from vinyl, allyl and methallyl esters having a long carbon chain, (d) acrylic or methacrylic acid, with the polymer being selected from: - graft copolymers which are obtained by grafting on vinyl esters, acrylic or methacrylic acid esters, singly or in a mixture, and copolymerised with acrylic or methacrylic acid, on an etherified or esterified polyalkylene glycol, or on an oxide of a nitrogen- containing polyalkylene glycol; - the grafted and crosslinked polymers which are obtained by copolymerising a non-ionic monomer, acrylic or methacrylic acid, polyethylene glycol and a crosslinking agent; - ter-, tetra-, penta- and higher polymers of a monomer of the formula <IMAGE> in which R1, R2 and R3 denote hydrogen or methyl, and n has the value 0 or is an integer from 1 to 10: - a water-soluble monomer of the formula <IMAGE> in which R' denotes hydrogen or methyl, Z denotes a straight-chain or branched alkylene group which is optionally substituted by one or two hydroxymethyl groups, m has the value 0 or 1, R4 is hydrogen or -COR6 (R6 = OH or -NH-R7, with R7 denoting hydrogen or -Z-OH), R5 denotes hydrogen or methyl, when m = 0, or R4 and R5 denote -COR6 when m = 1; - acrylic or methacrylic acid, where appropriate together with one or more copolymerisable monomers; - N-tert-butylacrylamide, N-isopropylacrylamide/ acrylamide, methacrylamide/acrylic and methacrylic acid/N-vinylpyrrolidone terpolymers; - water-soluble polymers of acrylic and methacrylic acid and copolymers of acrylic or methacrylic acid with a monoethylenically unsaturated monomer;- polyacrylamides which contain carboxylate groups; and - copolymers of from 40 to 90 mol% vinylpyrrolidone, from 40 to 50 mol% vinyl ester and from 20 to 30 mol% acrylic or methacrylic acid; (e) ethylene-α-β-carboxylic acid, (f) allyloxyacetic acid, methallyloxy acetic acid, 3-allyloxypropionic acid, allylthioacetic acid, allylaminoacetic acid, vinylacetic acid, vinyloxyacetic acid, crotylacetic acid, 3-butenoic acid, 4-pentenoic acid, 10-undecenoic acid, allylmalonic acid, maleamic acid, itaconamic acid or N-mono- or N-di- hydroxyalkylmaleamic acid or -itaconamic acid, with the exception of anionic homopolymers of acrylic acid which are crosslinked with a polyfunctional reagent, and in that the treated keratin material is not subsequently rinsed.
