In this paper, we investigate the shadow and optical appearance of the hairyReissner-Nordstr\"{o}m (RN) black hole illuminated by two toy models of staticaccretion. The hairy RN black hole describes the deformation of a Schwarzschildblack hole due to the inclusion of additional arbitrary source (scalar field,tensor field, fluidlike dark matter, etc.), which is characterized by theparameters: mass ($M$), deformation factor ($\alpha$), electric charge ($Q$)and the additional hairy charge ($l_o$). We find that for the hairy RN blackhole, the event horizon, radius of photon sphere and critical impact parameterall increase as the increasings of $Q$ and $l_o$,but decrease as $\alpha$grows. Furthermore, the three characterized parameters are found to havesignificant effects on the photon trajectories, and shadows as well as imagesof the hairy RN black hole surrounded by the static accretion disk andspherical accretion, respectively. In particular, both $Q$ and $l_o$ havemutually reinforcing effects on the optical appearance and shadows of the hairyRN black hole, which implies that we may not distinguish the electric chargeand hairy charge from the shadow and image of black hole in this scenario.Additionally, because of the competing effects of the charge parameters ($Q,l_o$) and the deviation parameter $\alpha$ on the observed intensities ofbrightness, the optical appearance between the hairy RN black hole and RN blackhole could have degeneracies, indicating the indistinguishability.
