I recon this is the right place for this question.
I've done a few Aiko Toon renders and the question of hairfits is was not really a problem.
Aiko Toon

IMO you can basically get any hair to fit anybody with the minimum of fiddling.
Either use the hair morphs to tweak to fit Aiko, or just resize it along the axis's you need to, ie. if it is too small or big along one or more axis, scale it . You can usually get pretty close to a perfect fit.
Fitting hair to characters is the least of my problems when putting a scene together, compared to lighting, shadows, composition, etc, which are the biggies.
