Question: Would there be a synergy with Topical Spironolactone and Nizoral? And is Topical Spironolactone (5%) as or more effective as Propecia in preventing/slowing MPB?
Answer: Propecia is the most effective individual treatment in preventing and reversing hair loss. Spironolactone is not a licensed treatment for hair loss and has no clinical efficacy for the treatment of hair loss.
I don’t think there should be any problem using Nioxin and then Nizoral but I would get in touch with the people you purchased the products off to make sure as we do not sell either of these.
