You might need to define "fast" a little more.
CC3 will allow you almost completely control over all parameters of shaping the head but will require you to have some outside skills in order to texture it (or some other program). It comes with textures, of course, but editing those is limited. Note that it IS free as long as you don't buy the Pipeline version (that version allows you to import avatars from Daz).
CrazyTalk Pipeline (not the basic version) will allow you to take images and create heads from those images quickly but the shaping is very limited. It will cost you money but you can also use it in conjunction with CC3 by exporting the heads and applying them to CC1/2 characters inside of CC3 and then further shaping them.
If *I* were doing this I'd use the freeware Daz along with a plugin called Headshop which takes images and creates heads from them similar to CT (but far easier and better) and then import them into the Pipeline version of CC3. You would have to buy Headshop but it's better for this purpose than CT by far.
Regardless of how you end up with the heads in CC3 you can't export *just* the head -- you can "hide" whatever portion of the mesh you want and export it, but the entire figure is still there (although in Maya you could delete the stuff you aren't using easily).
