I had lipo on my neck and chin. I have a five-o-clock shadow today and noticed there are 3 small spots (.25" diameter) of no hair. Is this the cause of the lipo? Will it ever grow back (not that I care--just curious)? There are 2 spots...and a couple "lines" (1 inch) of hairlessness. It hardly noticeable. I am 7 weeks out from sugery. Yes, I will be asking the doc, but its the holidays. Will ask him on Monday.
