NASA's mission was to go to the moon, but along the way they they discovered scratch resistant lenses and memory foam. I have both in my house right now.
The point is a discovery is something new and beautiful, no matter what the reasons for looking were. I can easily imagine some offshoot of this technology fixing some other skin condition like shingles or eczema.
As for the "this helps people's suffering" vs "quit whining and just shave your head" argument, I started balding at 14. I'm happy with my shaved head now, but at the time it started it felt like motherfucking Armageddon. Suddenly girls were a terribly important concern and I looked like a radiation accident. I wouldn't wish that kind of social suffering on anyone. Especially an awkward 14 year old fer chrissakes. It was miserable.
That being said, I greatly enjoy my shaved head now and if this treatment were to become available I wouldn't take it. Being hairless (once you're the right age anyways) is actually rather nice. You look just fine in the morning, rain doesn't bother me because I have no hair to mess up, and driving with my windows down feels wonderful in the summer.
