FAO Dudemon:
I don't think wigs are great, but you seem like someone who'd actually be able to benefit from them. Why?
- You're in your 40s, and therefore won't face the challenges many younger guys do to stay concealed (e.g. fights with mates, rough and tumble, team sports with showers).
- Your hair already looks cack (according to yourself). If people laugh at you for what's on your head already, you have a lot less to lose.
- You have a hair transplant scar, so shaving isn't such an easy option.
- You live as a self-confessed hermit nowadays, so you easily have the couple of hours a week required for maintenance.
- For the same reasons, you have less people to 'shock' with the sudden change. You're in college, so when you graduate you'd have a fresh start to give it a go.
I don't know where you read about glue melting, but there are plenty of glues and tapes that wouldn't melt at the equator. These are medical-grade adhesives; you could attach an arm with some of them.
I don't know why you don't at least try it. Obviously it's not a perfect solution, but in your situation it could offer you a way to get over this. You don't have much to lose, do you?
