and b) from about 20% to about 85% by weight of the first composition of at least one clay selected from the group consisting of Aluminum Silicate, Calcium Silicate, Magnesium Aluminum Silicate, Magnesium Silicate, Magnesium Trisilicate, Sodium Magnesium Silicate, Zirconium Silicate, Attapulgite, Bentonite, Fuller's Earth, Hectorite, Kaolin, Lithium Magnesium Silicate, Lithium Magnesium Sodium Silicate, Montmorillonite, Pyrophyllite, Zeolite, or mixtures thereof; with a second composition comprising a liquid shampoo to form a cleansing composition, wherein the first composition and the second composition are combined to form a cleansing composition at or near the time of use; (2) applying the cleansing composition to the keratin fibers; and (3) optionally rinsing the cleansing composition from the keratin fibers. ### Claim 2 (depends on 1) The method of claim 1, wherein the carbonate or bicarbonate salts of alkaline metals or alkaline earth metals are selected from the group consisting of sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate, sodium bicarbonate, potassium bicarbonate, magnesium bicarbonate, calcium bicarbonate, or mixtures thereof. ### Claim 3 (depends on 1) The method of claim 1, wherein the first composition comprises from about 10 to about 40% by weight of the at least one carbon dioxide-generating compound, relative to the total weight of the first composition. ### Claim 4 (depends on 1) The method of claim 1, wherein the first composition comprises from about 60 to about 85% by weight of the at least one clay relative to the total weight of the first composition. ### Claim 5 (depends on 1) The method of claim 1, wherein the second composition comprises at least one surfactant selected from the group consisting of anionic surfactants, non-ionic surfactants, amphoteric surfactants, or mixtures thereof. ### Claim 6 (depends on 1) The method of claim 1, wherein the first composition comprises at least one carbon dioxide-generating compound selected from the group consisting of sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate, sodium bicarbonate, potassium bicarbonate, magnesium bicarbonate, calcium bicarbonate, or mixtures thereof; and wherein the second composition comprises: i) at least one cleansing surfactant selected from the group consisting of anionic surfactants, non-ionic surfactants, amphoteric surfactants, or mixtures thereof; and ii) optionally, at least one conditioning agent. ### Claim 7 (depends on 1) The method of claim 1, wherein the first composition comprises: a) from about 10 to about 40% sodium bicarbonate relative to the total weight of the first composition; and b) from about 60 to about 85% magnesium aluminum silicate and/or kaolin relative to the total weight of the first composition; wherein the second composition comprises at least one conditioning agent; and wherein the weight ratio of the first composition to the second composition ranges from about 1:7 to about 1:1. ### Claim 8 (depends on 1) The method of claim 1 wherein the first composition comprises: a) sodium bicarbonate; and b) from about 20% to about 85% by weight of Magnesium Aluminum Silicate and/or kaolin relative to the total weight of the frist composition, wherein the second composition at least one cleansing surfactant to form a cleansing composition. ### Claim 9 (depends on 8) The method of claim 8, wherein the first composition comprises: a) from about 10 to about 40% sodium bicarbonate relative to the total weight of the first composition; b) from about 60 to about 85% magnesium aluminum silicate and/or kaolin relative to the total weight of the first composition; wherein the second composition further comprises at least one conditioning agent; and wherein the weight ratio of the first composition to the second composition ranges from about 1:7 to about 1:1. ### Claim 10 (depends on 1) The method of claim 1 wherein the first composition comprises from about 40% to about 85% by weight of the at least one clay relative to the total weight of the first composition.
