After years of styling stars like Mary-Kate and Ashley Olsen, Lea Michele and Emma Stone, Sarah Potempa found herself getting the same question from celebs and editors alike: How can I get perfect, beachy waves? Though explaining it was easy, teaching clients to do it for themselves using a curling iron, well, was not. So Potempa and her sister created the Beachwaver, a ceramic curling iron that rotates from end to root with the push of a button. Here’s how it works: grab a small section of hair with the beveled clamp, hit the “Go” button and let it wrap your hair to the root. Hold for 10 seconds, release, and voila — easy, California-style hair (you can catch a video tutorial here). Potempa will hit QVC at 2 p.m. and 9 p.m. EST on Saturday to sell the iron, and the Beachwaver — plus a comb and matching clips — is available now for $179 on qvc.com.
