Angie, I'd be surprised if it was exactly the same when you washed it, but it depends on what you're looking for really. Personally, I was dreading doing the treatment because I hate having my hair poker straight and flat, but actually, it looked alright and I got a lot of compliments. I was still relieved when I could wash it and I haven't really used the straighteners for over a month now. What's your hair normally like? Curly? Frizzy? If you've had problem hair before, you'll probably find you're very happy with the results. If you're just doing this because you want perfectly straight hair, but haven't really had problems with frizz, then I don't think it's as impressive. My hair would still be quite wavy/curly if I left it to dry naturally, but when I blow dry it, it goes very smooth and practically, completely straight.
Also, I've found the last couple of times I've washed my hair, it's less greasy. I think it's because the treatment is probably wearing off slightly, but I've just started adding a little more conditioner and it's gone back to being frizz free.
So if you have hair like mine, I'd say for the first 3 or 4 weeks, stick to just a tiny amount of conditioner and then after that, just add a little more.
I was panicking slightly a couple of weeks or so ago, because I thought that was it. I think you just need to read your hair as you go along.
Any other updates?.......
