I know this is a bit of an old thread by now, but I just wanted to update and say that I got the Ouidad cut!
I was pleasantly surprised by how much I like it. Honestly, I can now see the benefits of the carving and slicing. The waves really do puzzle into each other nicely and my hair is springier, curls/waves up nicely and I can now get 2nd and 3rd day hair with no effort at all. It just has such a nice shape to it. I will say that my hair is fine and the stylist did not do an excessive amount of carving. If anything, my hair now looks fuller and doesn't get as weighed down as it did before.
Initially, there was a bit more length taken off than I wanted, because the underneath part of my hair is much straighter - so he cut the underneath layer shorter to avoid that straggly straight ends effect I had going on before. And to do that, more length needed to come off than I realized. But honestly, my hair looks much better at this length. It moves, and it has much more body.
And he even said, that I won't need to get it cut now for at least 6-9 months or even more. So that was good. It was pricey, but I won't have to get it cut for a while.
Overall, a very good experience. I saw Vincent at the NYC location.
Oh, one more thing....I did straighten it the other day to see how it would look, since I do that every few months or so. It still looked good. No unevenness that I had with the Deva cut when I tried to straighten. But I don't do it much anyway...too much work, lol.
Hope this helps anyone who may be on the fence.
