This whole process takes time. People have to be patient. I have been on the big three, and dermarolling for 9 months and a half. I have been needling longer than everyone in this thread. The only thing is that I have been buzzing my hair. I can tell you that I have great coverage everywhere now (except parts of the crown). How do I know that? I appear as a full head with some crown thinning when I'm not under harsh lights. I have documented about 30 pictures of my longer hair, from before treatment. I'm excited to grow it out back to that length within the next 2-3 months, and then show all of you.
