This hairstyle is one that incorporates finger waves into a twisty bun at the base of the neck.
This model has a very deliberate side part and the sides are finger combed downward toward the ears to almost look like a short bob but actually this is an updo. Strong hold hair products make for a wet look and defined bends in the strands produce a ripple effect. If you are after an edgy flapper style then this might be something of interest to you. It is a great way to make a faux bob if you have longer hair.
