Dr. Griffin (retired now) at Dermatology Associates of Atlanta, (404) 256-4457 , has a formula of mix of topical Dutasteride and Finasteride. I use it and the result is very good. https://dermatlanta.com/
Yes problem not many ship outside, as I’m in The United Kingdom.This is topical 0.05% Dutasteride and 0.2% Finasteride together with or without Minoxidil. They can customize for you. No PG, with or without Retinoic acid etc. I found that my scalpel has allergy reaction to PG, Retinoic acid and Minoxidil and they can change the formula for me. I do not know if they do ship outside US.
