There's nothing really vain about wanting to look good. Eat the right foods, exercise, everyone _should_ be doing the basic things that make you look good. Cosmetic industry is slated to be valued over a trillion in the next few years, and that includes a lot of snake oil; good research that displaces snake oil remedies is a good thing. And I'm more than happy to see my tax dollars go into research that looks into baldness, even if only for folks who simply want hair.
