Cosmetic agents for temporarily reshaping keratin fibers, particularly human hair, containing in a cosmetic carrier at least one starch modified with propylene oxide, the starch having an average molecular weight (weight-average) of 50 to 2,500 kDa and a propylene oxide content of 4 to 6 wt. % (based on weight of the starch modified with propylene oxide), wherein the agents achieve styling with a good degree of hold and elevated flexibility. The propylene oxide-modified starches are based on renewable raw materials. Here, effective styling agents for hair can be provided without having to rely on setting polymers obtained from fossil fuels.
