Most Deva stylists cut straight hair to so I wonder if you wouldnt do better to go back to her to help you even out the cut. I would worry they would cut too much in trying to even it out. My guess would be it would take a couple cuts to even it out if its very uneven.

My Deva stylist said there is more to the cut than just curl by curl. It was different than what I pictured curl by curl to be.
