I'm 41 and I've tried many treatments -- some marginally effective, most cost prohibitive -- and I've learned that the effective ones consistently induce a shedding phase during the first two months. The fact that I've gone through a significant shed within the first 7 weeks of needling tells me that desirable results are likely. There's no improvement to report yet, but I'm familiar enough with my shedding patterns to know that growth is imminent. I'm using the Dr Pen A7, which is a pain in the *** because it's wired, but the speed is 17,000 per minute and the 12-pack needles are thin. https://gzekai.com/dermapen-drpen-ultima-a7-p00082p1.html I'm considering selling it for a wireless pen. I'm not considering a Derminator since I don't see the advantages and I don't think microtearing is the concern everyone thinks it is.
