OK, deep breaths—we promise this isn't as difficult as it looks. The fishtail braid is just like a normal three-strand braid, where you're constantly pulling outside pieces inwards, towards the middle of the braid. But instead of three sections, you've got two. To start, divide your hair in half, gripping both sections in each hand. Then, with your index finger, pull a half-inch piece of hair from the outside of the left section and cross it over, nestling it on the inside of the right section. Repeat on the other side, pulling a piece of hair from the outside of the right section and crossing it over to the inside of the left section.
