Too expensive, and some people can't get faces like that. The paper bag idea is better. Or just a mask that looks like a model's face would work. Besides, the bag idea is mostly for the hair, not the face. The hair matters more to women, and I don't see plastic surgeons giving hair back to NW7's. Do you?
Never mind that, though. I got a better idea. Dutasteride 500mg pill. I was just looking at a graph. While measuring serum DHT with different doses of Dutasteride, they found that the group that was given 10mg a day for a month had almost zero DHT even 50 months later. Why pop a pill every day when you can just take one 500mg pill? DHT problem solved. And I bet it is cheap to make, too. They just charge extra to pay for the research.
