My current stack is minoxidil 5% twice a day and topical finasteride 2.275mg/ml once a day (I tried oral finasteride for 6 months it was working but started developing gynecomastia so had to stop), my question is should I buy a derma pen or derma stamp? What length? And how many times should I use it? I feel like I couldn’t find a definitive answer on this topic everyone is using something different, with a different frequency and so on.
So I’d like to know your thoughts and opinions on this matter
