A no‐go theorem in flavor symmetries is reviewed. The theorem asserts that we cannot bring any flavor symmetry into mass matrix model in which number of Higgs scalars is, at most, one for each sector (e.g. Hu and Hd for up‐ and down‐quark sectors, respectively). Such the strong constraint comes from the SU(2)L symmetry. Possible three options to evade the theorem are discussed.
