Until yesterday I used to have long hair. Due to unusually high tempetures I started having problems with the skin on my head. So, to avoid problems. I shaved it clean and it will remain that way until the skin in treated.
Now that I'm bald, I now know what's it's like. It sucks. My old hair suited me perfectly. It was messy just the right amount, perfect length, made me look different than the rest and handsome as hell. Every girl would look at me where ever I went to. Compliments floating over the air, jealous looks from other men etc. etc. It made me feel powerful.
But most importantly, it suited my personality and clothing. It was perfect! But now it's gone. I hate bald me. I will never look back at this bald version of myself.
It feels weird. I don't feel that bad but still it's disheartening.
I would bet that this isn't the last time that you get unusually hot temperatures. Between this problem possibly returning and male pattern baldness, you'll probably face another time when you're cutting your hair short.
That being said, adapt! Experiment with different facial hair styles, find a cool new hat (but be normal - don't get something awful like a fedora) or sunglasses. Just because your hair has temporarily changed, it doesn't mean that you're a different person
