Trump said on Friday he "very well might" make a run for president under the Reform Party banner but had not made a final decision. "I'm looking very seriously if I can win," he told reporters. "And if I can win, I believe I can do a very good job."

Finasteride was originally prescribed to treat enlarged prostates in men, before it was discovered that a side effect of the drug was an observed reduction of male pattern baldness.

It is now prescribed by dermatologists to treat male pattern baldness, and is one of only four treatments that can be used to combat the condition.

This is only one piece of the puzzle when trying to understand the structure of Trump's hair, however. Hair surgeon Dr. William Yates has said that it's likely Trump's look can be attributed to an early version of hair transplant surgery, or an expensive weave.
