Shouldn't the tag be split up or a subdivision created between those that are resting on the head and those that are wrapped around the hair? They aren't really the same thing.
Even if we create separate tags they're all still towels; and for the ones that aren't really (like an honest to goodness turban or other headgear), they just shouldn't be tagged towel.
So implication done, but go ahead and create a tag for the different styles.
