I saw this style on Pinterest a while back and tried it out and it was one of the easiest styles while still being a bit different than just a normal braid. I love it for first day hair when it is a little flat and not wanting to cooperate..
This one barely even needs a step by step, but follow below!
1. Pull you hair into a pony and secure with an elastic. I created mine so it was directly in the back of my head, but wear it on whatever part of your head you think suits you best :)
2. Take a small part of your ponytail and wrap it around the elastic. Secure this with a bobby pin.
3. Create a three strand braid in your pony tail and secure it with a clear elastic.
4. Pull at the braid so that it looks thicker.
