  It is shown, using results of direct numerical simulations, that the
spontaneous breaking of local reflectional symmetry (and corresponding
localized kinetic and magnetic helicities) can dominate chaotic dynamics of the
small-scale MHD dynamo in the Rayleigh-B{\'e}nard convection, in kinetically
forced flows under strong stratification, in the near-surface solar convection,
and in kinetically forced flows at large magnetic Reynolds numbers. The notions
of deterministic and helical distributed chaos have been used for this purpose.
The coexistence of large- and small-scale dynamo mechanisms and applications of
the obtained results to quiet and active regions of the solar photosphere have
been briefly discussed.
