I've been using Dr. Lee's 5% minoxidil in the morning and 15% Xandrox at night for about 6 months now. I think its too soon to tell if they are working for me. I recently have seen a few posters on here joking about Lee's validity. I was always under the impression that his products were very good, and that he was extremely professional. I am just wondering everyone's opinions on Dr. Lee as well as any feedback on their success (or lack thereof) with his products (particularly Xandrox 15%.) Thanks!
