Here's an interesting economics question that's a bit broader in scope than a lot of questions on here.
I like to go clean-shaven. But razor blades keep getting more and more expensive, and that's not likely to change since they're literally the archetypical example of the "razor and blades" profit model.
There are various businesses that use electrolysis, lasers, or other techniques to permanently remove unwanted hair. As I understand it, such services are more commonly used by women, but it occurs to me that I could probably get this done for my face. If such a service means paying for an expensive treatment once and never buying razor blades again, there would have to be a break-even point, after which I'm saving money for the rest of my life.
Is there any economic data available regarding whether this is a good long-term idea?
