I don't think any of us has tried it. It's way too expensive for one thing... and for another, it's too vague. It's not designed for hair loss, there have been no reputible studies done on the drug to make it even an option. The 2 worst people to be are: 1) The first to try a medicine, and 2) The last.
But feel free. My opinion is that it's not worth the time or money to
There's a bloke by the name of Richlocks who was using RU. He's over at hairlosshelp.com. Go take a look. He stopped using it though due to systemic side effects, but he thinks that he's a rare case.
