Welcome to the forum, sibbs! Lots of great advice to be found here!
Sounds like you have a good plan. As mentioned, you could also grab a pair of clippers and buzz it down yourself if you wanted to. I already had a pair of clippers since I was cutting my own hair.
Anyway, welcome to the site. Don't sweat the hair too much man. What's more important than the hair is the way it's worn. Think about the Mustache. It can be a Moles-tache or it could be a Porn-stache, or a Cop-stache.
Sibbs, first of all Welcome to SBG.
Secondly, Read all the posts that they have on this forum about Head shaving.
Third, Just do it, and if you don't like it, it will grow out.
I will be the first to tell you that Shaving the Dome has it bad moments, i.e. nicks, bumps, ingrown hairs, etc.
but hey you might love the sly look just like 99.99% of the people on this forum do, but you won't know for sure till you do it.
We are here if you need support, hey there are even a couple of Athletic Supporters on this forum
Hey Sibbs, welcome to the family
A late welcome to you sibbs, glad you joined up.
As the other guys have said, maybe have it buzzed down so you can get used to it.
After that you can decide if you want to go all the way. Most guys here have found they just couldn't wait to shave it all off, once it was that close.
Good luck and keep us posted.
Sibbs, Welcome to SBG!!! I'm a newbie here too, but not a newbie to being sly.
I can understand your feelings about going bald at such a young age, but my philosophy is if it's inevitable, then embrace it. My advice would be to gradually work your way to a shaved head. Start with a 1/2" buzz and every two weeks go 1/8" lower until you use no guard. That way you, and everyone around you will get use to "the new you". I think that once you go sly, you'll realize that it's the best thing you'll ever do.
