Abstract: Hair treatment compositions include—based in each case on the weight thereof—0.0001% to 10% by weight at least one oligopeptide having at least one Glu-Glu-Glu amino acid sequence, wherein the amino group may be free or protonated and the carboxyl groups may be free or deprotonated, and 0.0001% to 10% by weight at least one proteolipid of the formula (I) in which R1 is a straight-chain hydrocarbyl radical having 8 to 22 carbon atoms, R2 is (—CH2)y—CH3, with y=0 to 22, Y is —H or —OH, X? is a physiologically acceptable anion, Hy is an oligopeptide residue from keratin hydrolysate, and x has values from 0 to 22. In these compositions, proteolipids and oligopeptides have mutually enhancing positive effects on the hair and the hair follicle.
