2. A process for the nontherapeutic treatment of keratin fibers, comprising: applying to said keratin fibers a rinse-out hair conditioner composition comprising: (i) 3-aminopropyltriethoxysilane in an amount ranging from about 0.2% to about 5% by weight, relative to the total weight of the composition; and (ii) potato starch acetate in an amount ranging from about 0.5% to about 5% by weight, relative to the total weight of the composition; and rinsing the composition from the keratin fibers after applying the composition to the keratin fibers.

3. A process for shaping human hair, comprising: applying to said human hair a rinse-out hair conditioner composition comprising: (i) 3-aminopropyltriethoxysilane in an amount ranging from about 0.2% to about 5% by weight, relative to the total weight of the composition, and (ii) potato starch acetate in an amount ranging from about 0.5% to about 5% by weight, relative to the total weight of the composition; and rinsing the composition from the keratin fibers after applying the composition to the keratin fibers.
