.1. Turn on flat iron to HOT!! You will need the heat or this won't work very well. This is a no brainer, but make sure your hair is DRY. Please don't fry your wet hair on my account. I did this on second day hair.
.2. Part hair into sections (thick hair may need more sections).
.3. Braid each section and fasten with a rubber band.
.4. Flat iron each braid starting at the top of the braid. Make sure to go slow. I actually found I got a better wave if I clamp and hold the top of the braid, move down to the next section of that same braid, and so on down to the hair tie. Do not untie. Repeat to same braid so each section of the braid is clamped twice.
.5. Move on to next braid and repeat step 4.
.6. Repeat until each braid has been "clamped" four times (or two rounds of two series of clamps!)
.7. Using a lightweight hairspray, get six-twelve inches away and spray your entire head lightly.
.7. Wait a few minutes.
.8. Undo braids.
.9. You're done!
I like my "beach" waves more on the hippie side, so it becomes a really loose wave like the photo above. You can do more clamps or even blast with a blow dryer after the hairspray for more of a defined wave. If you want something kinda crazy, after clamping you can even wrap the braids LOOSELY around a curling wand. (Make sure the wraps aren't too close to one another on the wand)
My hair waves pretty easily except for the top of my head ((where it counts)).
This braid trick does it perfectly!
Good luck and I'd love to hear your feedback :)
