Hair Removal Idea? Please Help?

I have hair on my back. It used to be horrible. It went away somewhat, but its still enough to drive me batty. This summer, if I spent many hours in the sun with my back facing the sun, would that help kill the hair follicles or something? I'd sunscreen the rest of my body, sure. Laser hair removal is all about removing the hair with heat, by destroying the follicle.... If I did this progressively with the sun, maybe it would work? All the variables make sense to me? What do you guys think? And yes I know, the sun AGES your skin horribly, but I honestly don't care if I have an ugly back... from the sun thing... as long as the rest of my skin is ok...
