Maybe if you get a better Deva cut than I managed to, but mine was a hot, scraggly mess, especially when straight after I had supposed Deva cuts by two different stylists.
Really, I'd think that might be somewhat the case with any Deva cut - what follows the curls and looks good curly may not when straight. I've heard others besides myself with that complaint.
Good luck whatever you decide!
