Double perturbation theory is used to calculate the form of the correlation hole in polarized and unpolarized dense electron gas. The analytical dependence on the polarization of the correlation hole at the origin is obtained. The normalized hole depth at the origin is minimal for the unpolarized gas. The correlation hole is always negative. It can be adequately described at the short range by the product of a spin-independent and density-dependent function on the uncorrelated pair-distribution function.
