Analysis (whoo, scientific): Legolas gets a different hairstyle! The hair is combed straight back, with a circlet going around half of the head. The sides of the hair are pulled back into a small fishtail braid, with the ends wrapped with a piece of hair to hold it.

Directions: Comb the hair back, and take a very small piece of hair from each side of the head, just above the ears. Begin braiding the fishtail, using a couple new pieces from above the ears before continuing the braid with the hair you already have. Tie it off with a small elastic a few inches from the ends, using a small piece of hair to wrap around the elastic and hide it. That's it!
