I like this hairstyle for one as simple reason. Its easy and it just takes minutes.
Start by combing your hair to the side and securing it to the side with a little elastic. If you want more volume on top, you can tease it first.
Then separate the hair above the elastic and flip the hair up and thru the opening then pull on each sideto get a little more volume to it.
Move down a couple of inches and repeat the process. My hair was long enough to do this 3 times.
I like this for a quick on the go style. Try it out and tell me what you think.
