Reshaping compositions, methods or processes, and kits-of-part reshape keratin fibers. The reshaping composition is a non-reducing, non-oxidizing composition for keratin fibers having a pH in the range of 7 to 12, and comprising a) one or more organic alkalizing agents having a pKa of less than 9.0, b) one or more lipophilic compounds being liquid at 25° C. and atmospheric pressure, at a total concentration in the range of 10% to 80% by weight, calculated to a total weight of the composition, c) one or more surfactants, and d) one or more thickening agents.
