How do you get beach, tousled hair if your hair is dead straight?

it's a bit of a long method but works! have a bath or shower and after your bath or shower spray salt and water mix all over your hair ...and defuse it ..then re-spray with the salt and water mix and leave to air dry.this is a free method but a good brand of products is fudge..there long lasting,good quality and smell great! i could write out the directions of use,but they are clearly printed on the side of the bottle! hope i helped
