Zenmervolt...Ingrown hairs almost always happen when you shave against the grain, not vice-versa.
Some people have to shave against the grain to get a good result but, when you do this , believe it or not, you are shaving hair follicle with it...moreso than shaving with the grain.
I found another way to avoid ingrowns is to soak the razor in hot water while I'm in the shower. This lessens the bacteria present on the razor.
Anyway, I shave with the grain on my neck while my face receives the up and down treatment!
TOOLGIRL YEAHHH BABY!!!!!
