Which keratin smoothing treatment for curly hair which won't straighten just reduce frizz and make more wavy without losing volume?

[Jmangel]

Asking too much? Anyone had a good experience and if so, which brand or salon so that I can find the brand? I have 3a/b hair with a halo of frizz - would love a smoother look - 2b would be gorgeous with no frizz. I really wouldn't want a flat look though as I don't suit it.
Thanks in advance.

Have a look at nanokeratin website. I'm having it done in a couple of weeks.

Yes, pretty much that...makes it very much smoother/easier to dry smooth, but doesn't actually straighten or flatten on its own.

I've had 3, loved them. Sadly I don't know which brand it was as a friend did it for £70 each time! Shame she bloody moved to Dubai...

Do switch to sulfate free shampoo though, otherwise it won't last.

Thanks guys - off to find a local salon.
