That sounds really unlikely. It's really fiddly work, done mostly by feel. You're talking about really kinky hair, so you have to move very carefully through it, a millimeter at a time. It does not handle like a flat string. To do it in minutes, you'd have to be absolutely flying. I'm not sure I'd want a machine working that fast so close to my head.
