First wash the hair before conditioning it and dry the hair using a towel. Then separate the hair to create two individual ponytails and brush the hair at the crown without touching the bangs. Try to twist your hair near the crown till it becomes taut and secure the hair in place. Now separate the left out hair on the left side right side and twist both of them around itself. Keep the sections behind the ear using bobby pins smooth out the curls. Take clip out of your hair on the crown to separate it into left as well as right sections. Twist both the sections again and secure it behind the ears just like before. Make sure that your twist looks similar to twisted hair near nape of the neck.
