Soooooo. My hair is very weird. Idk. It’s kinda wavy but kinda strait. When I take a shower and don’t comb it when it’s wet it gets pretty wavy. But when I do comb it while wet it gets straighter and dries with only a very slight wave. When I brush it while dry the waves are not very defined and some pieces are straight while others wavy. How can I make it so my hair always looks wavy in all places?

This is my hair after letting it air dry without combing. ^ I want it so stay like this all the time but it won’t :(
