Mine's not really long at all, if I took a picture that wasn't zoomed into my jaw you wouldn't be able to even see it, but it's just really itchy. I never let it grow this long because of how terrible it is.
I get way more of a "neard" than anything. I don't get why the hair on my neck underneath my chin and jaw grows better/faster.
I had to shave mine. I was going to trim it to rid ourselves of the bad luck today but it was too short to even trim although it was horrifically itchy. Since this is my first year doing a playoff beard, although it is still a feeble attempt, I decided I will just shave after every loss but keep it growing in between wins.
I'm leaving mine. Last year I shaved after our first lost and it didnt change anything.. leaving it on no matter what.. even though its starting to look kinda funky.. as long as I fix the side burns I'll be fine.
