We threw away those horrid metal curling irons and traded their use for new ceramic ones that give more even heat and less damage.  Alessandra Ambrosio may have vertically curled sections of her hair with said irons or she may have likely used the dry, heat to cool method, both giving more definition to the finished, loose look with little to no frizz.

This model is Alessandra Ambrosio, a Brazilian actress who has curls pinned up on the sides to give a perfect demonstration of how the pros set in those ever popular vertical curls.   While we are not able to apply these without help usually, it's comforting to know that curling irons help to give a similar look.   Your vertically applied curls can be pinned to cool as well when the iron is removed.   Note the big curl on top which will give lift and fullness in this area.
