Actually, ratscloset hasn't revealed all that little trick can do. Any hairstyle that that has tails, clip bound falls, etc, can have the clips-barrettes-whatever as props, with a section beveled and subdivided to provide sufficient vertices for guide hairs. This can either be smartpropped to the head, a particular modelled hair prop or figure, or left as a parentable prop for use wherever. The only issues with this approach is making sure the transmapped hair texture aligns properly, so it looks as if the hair is actually contiguous, and adding a layer of constrained dynamic hair over the transmapped hair, for a little bit of body (take apart one of Adorana's more complex hair props, you'll see what I mean).

The downside is the number of hair groups you can wind up having to run sim time on, and you have to be careful in your styling. If the transmapped hair's geometry doesn't support the flow to the extra hair bits, then it looks like a kid who takes a costume hair piece and sticks it on with no thought of looking 'right' (wihch for comedy is just fine, but.....)
