      Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.
