It's not difficult to make your hair design. You don't need to go Berber shop for cutting your hair or for different design. You can do it by yourself so don't be afraid to try it. Follow the 5 steps as you can see in this picture or you can see here.
1) Flip hair upside down and whip it back up quickly.
2) Gather hair at at the very top of your head and start to make a ponytail.
3) Only pull hair half way through the rubber-band and secure.
4) Take one strand of hair and wrap it around the base of the ponytail to cover the elastic.
5) Remove just a pieces of hair by your face to make the look slightly messy.
