Congrats on your results, looks good so far.
I take 0.5mg of dutasteride every day and 1mg of finasteride, I would take finasteride everyday but I'm on an expensive regime and don't have enough money to buy finasteride everyday as it is the one I least need, taking both everyday I guess would give even better results but that's up to you.
Oral minoxidil is what was used when Minoxidil's hair growth capabilities was found. It is not approved for hairloss tho only as a hypertensive. I am going to start taking 10mg everyday (5mg in the morning and 5 at night). I personally think its better, as it does not frizz or damp hair like the topical does and some say it is more effective than topical. Most on this sub say against it though because it raises BP, I'm someone who throws caution out the window when it comes to this stuff so maybe I'm not the best person to listen to on this, this post may help if you are interested,
