The present invention relates to the use of an anionic or cationic ampholytic copolymer which is obtainable by free-radical copolymerization of a1) at least one compound having a free-radically polymerizable, a,ß-ethylenically unsaturated double bond and at least one anionogenic and/or anionic group per molecule, a2) at least one compound having a free-radically polymerizable, a,ß-ethylenically unsaturated double bond and at least cationogenic and/or cationic group per molecule, b) at least one free-radically polymerizable crosslinking compound which contains at least two a,ß-ethylenically unsaturated double bonds per molecule, c) if desired in the presence of at least one silicone compound containing a polyether group and/or a free-radically polymerizable olefinically unsaturated double bond, as rheology modifiers for compositions in hair cosmetology. |
