It sounds interesting however, it wouldn't be a bad idea to check body chemistry to make sure the hormone production isn't acting up. My daughter had that problem with her chin so my wife and I discovered that her hormones were all messed up. Sarah's still getting the lazer treatments but the hair keeps growing back.
As for me? Well, I have way too many grey hairs on my head so I'm not sure what to do. I suppose I could get my hairs lazered off then just shave the grey ones manually. Might make my head shaving sessions a bit easier.
