I've seen countless studies on the effectiveness of topical finasteride and they all look promising. Has anyone heard if topical finasteride has nearly as many sides as oral finasteride? Hasson and Wong have a pretty good deal going on for their solution. Just a little more expensive than minoxidil, but seems promising. I'd probably just be applying it to a small portion of my hairline. Do you guys think it goes systemic, and if it does, does it affect serum levels of DHT as much as oral finasteride?
