Hair treatment agents having in addition to at least one hair-setting polymer, at least one polyether of formula (I)T-K-A-K′-T′ (I),whereinA is a polyoxyalkylene chain comprising ethylene oxide units or ethylene oxide units and propylene oxide units, having a maximum of 50 wt % propylene oxide units based on the weight of A,K and K′ are, mutually independently, a connectivity chosen from a covalent bond or a molecule fragment having two free valences,T and T′ are, mutually independently, a molecule fragment having at least one substituent chosen from anionic residue or —Si(OR)x(R′)3-x residue, wherein R and R′ are, mutually independently, a (C1 to C4) alkyl group, and x is 1, 2, or 3,wherein at most one residue from T or T′ can also be a (C1 to C6) alkyl group, aryl group, aryl-(C1 to C6) alkyl group, (C1 to C6) alkoxy group, or (C2 to C6) acyl group.
