That are tons of things at least as good as finasteride without the nasty side effects. Did you check the Japanese study with nizoral cream ( not shampoo ) the results are as good as the finasteride posted by Hasson and Wong. Topical cetirizine, etc . Finasteride and dutasteride are dumb drugs, that will kill the most stronger androgen in the body and even this "new " topical version, according to the same Hasson and Wong, best scenario will drop it a 30 % , but many get an inhibition of more than 50 % , and we are talking about systemic inhibition.
Again, great for 1997, stupid , none sense for 2017.
