Spironolactone as Hair Loss Treatment

Dear Doctor,

there are many people suffering from hairloss, who use topical spironolactone as dht blocker. Do you think that it is an effective treatment against MPB? Is this a safe treatment or is spironolactone absorbed through the skin resulting in side effects? I thank you in advance.

Spironolactone can have significant sexual side effects in men. Finasteride 1mg (Propecia) works best with the least amount of side effects. I’ve written about spironolactone use here and reported on a clinical trial in Australia that recently started to treat hair loss in women here.
