Restructuring hair treatment agent

Abstract

Hair treatment products containing, based on their weight, 0.01 to 5 wt% of at least one specific alpha-substituted compound and 0.01 to 80 wt% of at least one straight-chain or branched, saturated or unsaturated hydrocarbon with 10 to 20 carbon atoms, lead to restructuring or a permanent or long-lasting internal structural strengthening of the keratin fibers, to a reduction, elimination or prevention of hair breakage or split ends, to the protection of hair fibers from moisture loss and to the improvement of the optical and haptic properties of hair fibers.

Claims
