Upper lip, chin, under chin and just recently side burns. Although where I already had side burns (next to ears) got thicker before anything else. My stache randomly stopped coming in, and I started getting chin hair, then that progressed to under my chin (both places are much more obvious than anywhere else on my face). Then maybe a month ago I noticed thin and small lines of hair on each side burn area of my face. I have been on T since late September, 2013.
