Abstract
The pigment-containing foamable gel for temporarily coloring the hair contains from 35 to 98 percent by weight water; one or more gel-forming thickener that imparts a yield point to the composition; at least one pigment; at least one film-forming, hair-fixing polymer; at least one foam-producing surfactant and at least one propellant, in combination with a suitable aerosol package and a foam-forming device for foaming the gel. The concentration of the thickener or thickeners in the gel is selected so that, on the one hand, the viscosity of the gel is sufficiently reduced so that foaming of the gel is possible and, on the other hand, the yield point is at least large enough so that settling of the pigment is prevented. The easily foamable composition has a hair-fixing effect and temporarily colors the hair, providing a high color brilliance and lustrous appearance. The composition is washable from the hair at will and the color of the hair provided by it has good fastness to rubbing.
