update, Im about 4.5 months after adding dermarolling (now 1.5mm) to my regime. Prior to that I started minoxidil in June of 2020, and have been on zix for 17-18 years or so. Observations, some filling in at the corner of my temples, more hairs along my teenage hairline, everything is thicker. It's tough to say how much more hair is along my hairline, could be 30-50 hairs (which doesnt go far across the hairline). Also, several people have jokingly suggested I color my hair since it's so dark now - that to me tells me my hair is noticeably thicker.
My hairline is not by any means coming back with a storm, it's really slow. If anything I have these sporatic hairs now which I find a little out of place, it seems to be filling in but has a really LONG way to go. But I do see evidence of where my hairline used to be 20 years ago. Im hoping things will pick up though, it takes time to have an effect and then to grow through the scalp. So Im hoping by month 6 I'll have much more to report. Perhaps I only really started with a decent dermaroller 2 weeks into it, so mayby I have 2 full months to get to 6 months. 9 months is what I think will be my plateau mark, and 1 year will be my "I dont think I'll progress more than this". Anyhow, still early-ish days. I hope to report more gains in the coming months.
What I can say is that adding minoxidil and dermarolling to my zix regime has really made a difference. I wish I had started earlier.
