On the first look it seems the second one has wrongly asigned materials… and one a second look… the hair i black but have overlpping UVs and the dame material as the body … ??
I think the hair should have a different material… or some reorganized UVs…
Edit: no i was totally wrong about this… 
Edit2: no… no… in the origianl file the body and hair have different material… in the second the body and the hair have the same … so slect some and assign correct material like so:
