What are we allowed to bring to basic?

Hi, I am going to basic in the next year. I know this is early but I have really sensetive skin and very curly hair. So I was wondering what we could bring to basic training so that I don't have a flare up or trash my hair too bad. Also are braids into a bun allowed? I want to be able to test products on my skin now as long as I am allowed to bring them. I am going into the Army. Thank you :)
