^^like she said, your hair will be easier to achieve this on if you have a wave to it. if you dont want to use a curling iron, you can try running a frizz cream and some sort of setting gel/mousse through your hair while its wet, possibly damp if it doesnt tend to frizz a lot. Then you can either put your hair in two french braids and let it air dry, or you can take small sections of your hair and twist each up, until all your head is done. Secure them with bobby pin or rubber bands but that wont leave an indention. let that air dry also. when your hair is dry, let it down spray it with a curl enhancing hairspray or one for texture and body, and gently seperate the plaits or twists with your fingers. NO BRUSH! You should have a similar look. Sometimes even after this, you might have to put a few big curls in with an iron, but at least you wont have to do your whole head. Try different products for different kinds of hold. Hope it works!!
