Every budding super-villian knows that lasers have several uses: you can use them to try to slice 007 down the middle; point them at a large capitalist country and demand a ransom; blow up a small moon (but never, ever, point them at someone's eyes, because that is dangerous). But did you know you could use them for grooming? (Me neither. Maybe that's why I flunked out of Supervillian School.)
Instead of bristles, this Laser Hair Brush from Brands on Sale ($199.99) has both LED and laser simulators, which won't tame your troublesome locks, but do claim to provide "light stimulation" to help your hair grow richer and thicker.
I bet if notorious supervillian Lex Luthor had one of these, he wouldn't have been nearly so angry with Superman and his perfectly coiffed hair and spit curl.
