Is it MANDATORY for women entering the NAVY to cut their hair upon entering bootcamp?

Im considering joinging the us navy, and my hair is about 2 1/2-3 inches past my shoulders. my hair is EXTEREMLY thick and curly (almost coarse) and i know a short cut would not work for my hair. it would creat a havoc during my military training and would require more attention to it than needed.its easier to maintain long than it is short and put it in a neat tight bun. so what do i do? i hear every other branch except the navy dont have to cut their hair is this true?
