I recommend Airwrap.

The Airwrap was the most expensive item on my recent shopping list. Since my hair is very curly and loses its shape quickly even after using a curling iron, I decided to splurge on the Airwrap, treating it like paying for a hair straightening treatment all at once. It definitely lived up to its price, and I am very satisfied with it. I love that my hair looks bouncy and doesn't look frizzy when I use it.
