This is purely anecdotal. Dr Proctor may believe his stuff works, and it costs him a lot to make it, for all I know. But from what I can tell, those ingredients shouldn't cost much. You might try ginger shampoo from the body shop, it has Piroctone Olamine, which has some studies behind it. Also, salicylic Acid shampoo from CVS, can work in combination with nizoral shampoo. Dr Lee sells it as a regrowth shampoo, but you can put a dab of both on your head, mix it up and get the same results.
Finally, if there are a bunch of you that have great success with NANO alone, please post and prove me wrong.
Honestly, you should get some Rogaine, if it doesn't give you sides, and look into Propecia and Tricomin. Tricomin won't grow hair, but it will make the hair you have look a little healthier and stronger.
