Yep, the Business Hair is likely too long for your needs. That said, here are the results of what I was originally trying to do with that hair last night.

I rendered a bald version of M4, then another render with the highly modified and scaled Business Hair, and then brought both renders into Photoshop where I put both renders on separate layers. Some quick Eraser work to blend them together yielded the final result.

I had fun experimenting with these hair props/figures. Thank you, anupaum for inspiring me to play. I just wish I'd been able to point you to a solution!
