Abstract

The product for hair treatment includes a transparent pressure-resistant aerosol container and a device for making foam from an effective-ingredient containing composition contained in the aerosol container. The effective-ingredient containing composition contained in the transparent aerosol container has two clearly distinguishable liquid phases with a sharply distinct phase boundary. The two liquid phases consist of a hydrophilic phase and a hydrophobic phase. The hydrophilic phase includes water or a solvent system containing water and a water-soluble organic solvent, at least one cationic or cationically-active hair care ingredient and at least one organic or inorganic salt. The hydrophobic phase contains a water-insoluble, liquefied propellant gas and at least one water-insoluble, hydrophobic, oily or fatty substance dissolved in the liquefied propellant gas.
