Hair at the crown that is only just thinning is much more likely to see terminal hairs sprout back up in that area than the hairline. The hairline rarely gets much regrowth sans a few vellus hairs because the follicles have been inactive for too long to create terminal hairs again. In rare cases, like the God of hair regrowth "zeroheat", get on treatment very early and see wonderful regrowth, but that's very rare. I've come to accept the fact that I'll need a hair transplant at some point in the future if I want to get back to NW2 because I've been treating for nearly 9 months now, and basically have no regrowth at the hairline or temples. My hair in the back seems to be getting a little thicker, but that's it.
