Who says you have to only wear one? I want to wear three. I like my buns to be nice and messy. I don't mind if there are hairs twisting out all over the place. It looks nice all sleek and polished too, but sometimes you need to just not worry about it. I challenge you to try it.I always start with the top bun. I have my hair parted on the side and just sort of swept back with the hair. I think you can part it just about anyway you want. I have a tendency to twist my buns the same direction and when I pin them, I pin in a X . I use only about 3-4 bobby pins per bun. I usually rake my fingers along the sides to blend the part a little, give it some spray, and I'm out the door. Give it a try. This works with shoulder length hair too, you just might need to use rubber bands to hold the buns in place.
Have a happy hair day!
