Mohawkz Hair comes with 2 Highlight options.
Ones that highlight just ends, most of the  hair
With addition to make the *scalp* Higlighted.

The base model comes without any highlights, so if you just want 2 hair tones, aka hair and scalp, all you have to choose is the highlighted scalp option.

Will clip in some poses.
Scalp might look unnatural in some colors.
