Hello,
here my six months results. Start: pics 1,2. Three months mark: pics 3, 4. Six months mark: pics 5,6,7. Nothing impressive, but anyway something happened. Thicker and darker hair, and more density especially where some hair was already existing. I will keep going until 2 years mark and keep posting here.
My regimen: minoxidil 5% twice per day (around 2ml each time), dermarolling mildly at 0.75mm (0.50 in the first 4 months) every night for less than 5 minutes, just before applying minoxidil. Derminator2 at 2mm every 10/14 days going for blood with minoxidil applied 10 minutes after.
My story: 45 yo, used propecia with success for 10 years then dropped because of sides. Used minoxidil afterwards for few years with no success.
Note about being originally a minoxidil non responder: its hard to tell exactly. when I started using it I had a massive shed. never fully recovered. but I almost maintened afterwards for few years. after I dropped it, the situation worsened quicker.
