Yeah, C'n'M, I have regrowth in the temples from minoxidil, but it took a long year to recover a relatively small patch of real estate.
However, it was PRIME real estate... those upper corner temple areas of my widows' peaks, they have been rounded off by a good 3/4 inch or so. Instead of a very sharp and jagged edge up there, I have a cosmetically significant reclaimed area in those corners that have rounded that line down to something that no longer looks like Phil Collins.
Regrowth is still occuring, but is slow. Kind of a hair-by-hair basis, individual hairs along the hairline are slowly progressing, one by one, from dark vellous, to intermediate pube-like, and finally to terminal-looking. The progress is slow, but continuous. The hair cycling schedule of the scalp can take quite a long time before hairs completely cycle through, are shed, and a new minoxidil-enhanced hair finally takes the former hair's place.
