I talked with my old stylist where I used to live and this is what she said....

Typically, the way most people do a deva cut, your hair will not look as even straight. The reason for getting the deva cut is to wear it curly.

On my clients who wear it straight and curly, I even pull it out either dry or wet and do a more even cut as well as do a curly dry detail cut. That's just the way I do it though.

So..... I guess it won't look super even with the deva cut. But I have never been happier with my curly hair and I don't want to lose that. So, I'm going back to the deva stylist here and have her hopefully just make it a little better when straight but not lose the really nice curl pattern
