of course such redness is normal. secondly from my pov people should not apply any product right after woundig (1,5 and more) and should wait for 24h like the dhurat study. wounding itself release pge2, growth facotrs etc... Just let the wound heals itself. Of course a compound that target hair neogenesis is welcome but it's still random and maybe more advisable for people with advanced hairloss). People usually have results with just wounding device or wounding device+minoxidil (there are enough studies to prove this ).
that said I don't think you have AAG, it looks like a mature hairline people dream of at this age
