Add texture to hair by using a one-inch curling iron all around the head. To create beachy waves, pull on the curl while it's still hot, and then rake the curls with your fingers for a more undone look.
Part hair down the middle. On one side, start by doing a standard 3-strand braid on a very small section near the crown. You're then going to start a waterfall braid, which means instead of a normal French braid, you're only going to pick up hair from the top, letting the bottom strands fall free.
