Now, I have some questions to ask:
Should I do it?
Sounds like a nice idea. You'd be BBC, I'm BBC. Quite a few guys on here who don't have to shave their heads, but they like the style. Go for it.
Will it be very noticeable after I shave it? If you are already at a #2, take it down to a #1 for a week, then #0 for a week, then break out the razor. Good process.
Will it be too pale? It likely will be somewhat pale, but that fades over time. You're moving into summer in Columbia, so that should be good for it.
What can I do if I make any mistake/Regret it? You'll be back to a #1 in a week, Wear a hat for a few days.
What alternatives there are? Alternatives, keep the hair, and miss out on a wonderful experience of being bald. The smooth shaved head is a wonderful feel. The first month or so, you'll be rubbing your head a lot, Just taking in the new feel. But to keep it up smooth, you'll likely need to shave daily or every other day. Let the beard grow, if you can.
What should I consider?
What problems could I find? Can you afford the blades?
What kind of reactions should I expect? Probably nothing, or perhaps a few bald jokes. Lots of confidence.
What do you think when you see a bald 16 y/o? What will people think? I think .... now there's a guy who is willing to step out and be an individual. He can handle it. I think it looks sharp.
Any other advice?
