The Difference Between Slick Bald and Thinned
I often hear that new treatments won't work on NW7 scalps. I myself am not that, but even if my hairloss is much more forgiving in the future than it's been in the last few years, I could be by the time treatments arrive. So I'm wondering what the difference is between follicles on a slick bald scalp and particular follicles that don't grow hair on thinned scalps.
Now, I don't want people coming in here saying they're sure future treatments will cure all NW levels, anymore than I want to read someone's argument about why we'll all be bald forevermore. Just science, please. No guessing, only evidence based claims. Citations if possible. What is the difference between those follicles.
