i would go with spironolactone because it is an anti androgen and could help slow down male pattern baldness..folligen is more for scalp care to maintain a healthier scalp condition if I'm not mistaken.
what about alternate both?? lets say 2 days 5% spironolactone then one day Folligen and so on.. i was told that Folligen is used for its anti inflammatory properties which is another cause of hair loss due to the immune system attacking the hair follicle
