Quantum corrections in ultraviolet drive Higgs boson mass to higher values than we measure in experiments. This is the so called hierarchy problem. One can solve it by imposing conformal or scale symmetry. Nevertheless, Higgs mass must be somehow generated, which may be obtained by spontaneous scale symmetry breaking. We present a scale-symmetric extension of SM Higgs scalar sector in which mass scales are not generated by radiative corrections, but spontaneous breaking of scale symmetry when its Goldstone (dilaton) acquires a vacuum expectation value. We present how this vev can be reached via evolution of the fields in hot Universe and we show that coupling this theory to gravity stabilizes the solution.
