I prefer the bald look myself. However when I was a kid I had hair down to my jeans. I had all kinds of different hairstyles growing up. Rat tail about 10 inches long and braided with short hair, rat tail with the rest bald, a perm, dyed, a couple different Mohawk styles etc. pretty sure I had a mullet a time or two also
it’s just hair it will grow back so enjoy it before you have to fit into the super small box of standards a lot of society thinks we should fit in based solely on a poorly opinionated perception of how everybody should look! How boring life must be for some people or would be if everybody was the same. Same with tattoos, I am about 65% covered soon to be more. Society for the most part is scared to step out of that box and be themselves, fearing somebody who doesn’t matter in their life may say something or judge them. Just remember though, you still need to respect your parents while you are under their roof which obviously you do. Enjoy it and tell your dad he should get one
