I tried topical and had close to no response after about a year of using it. I tried oral and have had significant regrowth after about 6 months. I don't have any awards though, so my input on personal observations might be worthless to some of you.
Is it a cure? No, but it helped, in conjunction with a bunch of other stuff, to give me back some hair and enable me to grow it out enough to wear a little bit of concealer and have the total illusion of a full head of hair. I'd love to not have to use concealer any more, but honestly taking 10 minutes every 3 days to reapply concealer and enjoy how I look is worth it, and was made possible partially from oral minoxidil.
Currently on 10mg. Tried 5mg in the past, but increased dosage in hopes of better results. I'm prescribed blood pressure medication, so the amount it lowers my blood pressure is a non issue, it puts me in the 135/80 range.... down from 160/100. Considering swapping from 1x 10mg at night to 2x 5mg, spread out so I dose every 12 hours.
