More than 40 million American men suffer from hair loss. That means there’s a huge market for baldness drugs.
The most common are Propecia (finasteride), Proscar (also finasteride), and Avodart (dutasteride). Men spend $225 million each year on these medications.
Most men take the drugs, grow some hair, and do fine. President Donald Trump, for example. His doctor says he’s on Propecia and has no issues.
