We awarded the HairMax LaserComb the coveted top spot in our Top 10 Wildest, Wackiest Gadgets from the Back of Magazines list, and now the FDA has gone and awarded it approval for the masses. Shockingly enough, in the official trial 93% of participants saw an increase in hair growth. Yes, a product that purports that concentrated light as any type of effect on anything actually might work for once. Whaa?

I'm still beyond skeptical, but if you feel like using lasers to comb your hair and don't think $545 is too much to waste on such a questionable product, now you've got the FDA to blame in addition to yourself for your idiotic purchasing choices. — Adam Frucci
