This is a curled under bob hairstyle that will go on most humans. Some slight adjustments may be needed for toddler, senior and plus-size humans. I have included diffuse, specular and normal maps and the .mhmat file should get them all imported into Blender, where their properties can be adjusted according to preference and render engine. Illustration shows hair with Subsurf of two. Three additional colors are available in Materials.
