I was wondering what would be the best way to utilize products to stop hair loss. I’ve already started on the receeding hair line and a couple of months ago started noticing very slight hair loss at the top of my head. Could I use Nolvadex combined with Propecia and possibly a topical shampoo like Dr. Proctor’s Nano Shampoo at the same time. And what is the difference between something like Nolvadex and Propecia. Thank you.
