Last night, I wanted to cut my own hair and I used a hair-cutting-machine for that. I wanted to cut it short, about 1-2cm. In the middle of the process, the machine stopped working, I opened it for repair and put it all back together. But I forgot the spacer. When going on shortening my hair I wondered about how much more there was.
When I finished the back of my head, I looked in the mirror seeing that there's no hair left, except on my forehead and partly one of my sides. The damage was unrepairable, I so removed the rest too.
I work as a programmer and am a student. There are no strict rules on how to look, but especially in my environment, a shaven head is generally equally thought often as right-winged. I have the fear that people will see me and think I'm a nazi (which I'm certainly not). I also have no idea how to explain to my co-workers how something that stupid could have happened.
I'm full of shame right now regarding this issue. What's the best way to handle that confidently and professionally, without misunderstandings?
