Different visual references for the same hairstyle idea. These are examples, not fixed specifications.
A fictional young fair-skinned man wearing a Celtic-style tonsure with the front portion of the scalp shaved and longer hair retained behind the transition. The retained hair is shown with a loose wavy texture; the defining feature is the placement of the shaved front section rather than the curl pattern. The front and upper-forward scalp are shaved closely, while substantially longer hair remains behind the ear-to-ear transition.
A fictional older white man wearing a Roman-style tonsure with a cleanly shaved crown surrounded by a continuous ring of short hair. The retained hair is presented with a straight-to-slightly-wavy texture, but the tonsure geometry itself does not depend on a particular natural hair type. The crown is shaved to skin level while a short, even ring of hair remains around the sides and rear of the head.
