What's the appropriate dose of oral Min for a beginner?

23 year old newcomer here. I’ve been on oral min 1.25 mg and fin 1mg for about 20 days now. I’ve had a receding hairline for as far back as I can remember, but I never really did much about it apart from usual hair care (castor oil and scalp massages), but seeing as its gotten noticeable worse, I’ve finally decided to go for it and hop on min and fin alongside weekly dermarolling.

I’d say my hairline is a Norwood 3. It’s thick everywhere else apart from my hairline. I was originally going to just go with a dose of 2.5 mg minoxidil alongside my 1mg finasteride, but apparently 1.25 mg is enough to start regrowth/stop the hair loss.

I know it’ll take about 3 - 4 months before I see any visible results, but I’d like to know if I should increase my oral minoxidil to 2.5 mg or if I should leave it at 1.25 mg for the time being.

Any help would be greatly appreciated.

I’d leave at 1.25 and see how you feel, but 2.5 seems more common.
