The skull had a length between 70 to 90 centimetres (28 to 35 in).
It was longer than those of other rhinoceros, giving the head a deep, downward-facing slanting position, similar to its fossil relatives Stephanorhinus hemiotoechus and Elasmotherium as well as the white rhinoceros.
Strong muscles on its long occipital bone formed its neck hock and held the massive skull.
Its massive lower jaw measured up to 60 centimetres (24 in) long and 10 centimetres (3.9 in) high.

The nasal septum of the woolly rhinoceros was ossified, unlike modern rhinos.
This was most common in adult males.
This adaptation probably evolved as a result of the heavy pressure on the horn and face when the rhinoceros grazed underneath the thick snow.
Unique to this rhino, the nasal bones were fused to the premaxillae, which is not the case in older Coelodonta types or today's rhinoceroses.

The teeth of the woolly rhinoceros had thickened enamel and an open internal cavity.
Like other rhinos, adults did not have incisors.
It had 3 premolars and 3 molars in both jaws.
The molars were high-crowned and had a thick coat of cementum.
