The best part about straight hair is that you can try almost any haircut and your hair will fall neatly into place (lucky girl). But, if you want a cut that’ll add more volume to your hair and give it more movement (since straight hair can sometimes just sort of hang, you know?) ask for a haircut with a lot of layers. Fitzsimons says volume-creating layers are a much better option than all one length, since that can drag your hair down.
