I had the same issue, had been shaving it for about 10 years, was working on a shutdown and couldnt be arsed shaving it. Also let the beard grow a bit and was liking the length it got. Came into my work to have a "chat" with the GM from my old work after being away for 5 years, he didnt recognise me with the hair and the beard. Got the job and there were a few newbies here since the last time I worked here. I decided to shave the whole lot off at new year and got stopped by security when I came back after New Year.
At least I know that if I really wanted to I could go full Seaton Carew in a Canoe and disappear and be able to change my appearance markedly.
