We show that arbitrary multiparty quantum states can be made to satisfy monogamy by considering increasing functions of a bipartite quantum correlation that may itself lead to a non-monogamous feature. This is true for states of an arbitrary number of parties in arbitrary dimensions, and irrespective of whether the state is pure or mixed. The increasing function of the quantum correlation satisfies all the expected quantum correlation properties as the original one. We illustrate this by considering a thermodynamic quantum correlation measure, known as quantum work-deficit. We find that although quantum work-deficit is non-monogamous for certain three-qubit states, there exist polynomials of the measure that satisfy monogamy for those states.
