I keep thinking of having this done. Mine's going at the front (either that or my forehead is growing
...)
Only thing putting me off is; couple of years ago i got a number 3 or 4 and TBH it just made it look even my hairline even more "noticable" - kinda like the contrast where my hair stopped & my forehead started.
I think if you're gonna have it done, don't pussy around like i did - just go for the stubbly look.
Another thing; i think skinny pale blokes rarely suit that look. I'm gonna hang on till i get a tan & put on a bit more size (that's if my hair will wait for me)
