Sorry to be negative but I have to be.
So, I had my own haircut before left to the bootcamp. I had nice long hair.
In the bootcamp I saw afroamericans (the girls) don't have to cut their hair. They were even allowed to have WIG on the top of their hair so no one really saw how their own hair long. They don't even washed their head regurarly and they had a terrible smell. (we were required to shower every single day, etc so the Navy put attention for that)
I think it's a positive discrimination for them. Can't believe it
(other thing that few of them had their nature look fake nail during all the time, no one asked them to remove it.)
