The object of the invention is a hair-treatment agent in the form of a two-phase gel, containing comminuted particles of a firm and shape-retaining gel based on a carrageenan-containing aqueous base in a fluid polyol matrix. The gel is a clear product with properties of a hair wax or hair cream and it can be dispensed, sprayed or foamed from a suitable container by means of a propellant.

Two-phase hair gel

The hair treatment method includes applying to hair an effective amount of aqueous, alcoholic or aqueous-alcoholic hair treatment composition containing from 0.05 to 15 percent by weight of at least one as-yet-uncrosslinked hydrolytic precondensation product for forming an inorganic-organic hybrid polymer and optionally at least one film-forming hair-setting polymer, and subsequently crosslinking the as-yet-uncrosslinked hydrolytic precondensation product while the as-yet-uncrosslinked hydrolytic precondensation product remains on the hair to form the inorganic-organic hybrid polymer in order to provide long-lasting good hair setting. The hydrolytic precondensation product has an Si&mdash;O&mdash;Si network and is made by hydrolytically condensing at least one organosilane having crosslinkable groups with or without a network-modifying compound for modifying the crosslinking of the crosslinkable groups.
