After posting this picture on Instagram, I've received several inquiries on how to do this. Unfortunately, I couldn't find the original video tutorial for the life of me. So then I tried making a video myself, and well, that was just a disaster. But then! I gave it one last shot, and voila! I found the video again!
It really is the world's simplest way to create beach waves without any heating tools or hair products (though I do recommend a little hair spray spritz once you take it out. I've found it helps it last longer.)
Here's the front view (And another chance to see my new Stitch Fix tribal leggings that I'm thoroughly obsessed with - in case you don't follow me on Instagram and haven't seen my profession of love. Also, don't mind the pose. As much as I love the camera, sometimes it just makes me all kinds of awkward.):
And one last tip of advice: Don't be alarmed when you first remove the buns. Your hair can look a little cray. But just give it a few minutes, and flip your head up and down, and it'll settle down.
And great thing is, these waves last alllll day long. I had them yesterday morning until bedtime!
(And P.S. Can I please have this chick's hair?!)
