I have med. hair and i dont no what to do with it is strat with a little wave do you have any ways i can do it?

My hair is similar! mostly straight though! But I using finger comb in gel after a shower and then add mousse, do little messy buns all around my head. go to sleep. wake up. take them out. Shake my head and boom my hair is curly/diffused looking! It takes a bit of work on the mousse, gel, hairspray end, but it stays in pretty well and looks cute! Another thing to do is before you go to bed, with damp hair, braid your hair all over and in the morning, spritz with hairspray, take out, and you have a wavy hair do! Good luck!
