DIY salt water spray! Get those beachy waves without stepping foot on the sand <3 Just do this once in a while though cause my hairdresser said that too much salt water can dry out your hair :). I hope this can work as well as the ocean.
Beach waves: braid your hair in loose big braids. Twist one braid at a time and run a straightener over it. Repeat twice for each braid. Release hair tie and fluff with fingers and you get pretty simple beach waves.
