the drugs that are designed to prevent hair loss are 5-alpha-reductase inhibitors. So remember 5-alpha-reductase from the Guevedoces? Well, the people that discovered the Güevedoces, went on to do a lot of research on the underlying biochemistry of this really interesting molecule dihydrotestosterone. They identified 5-alpha-reductase. and 5-alpha-reductase inhibitors are the basis of most of the anti-hair loss treatments that are out there.
