Anyone try more than one Keratin treatment-including Gretchen!

I had one done about a month ago and it was called Tropic or tropical by Laslo. I'm wondering if anyone has tried another brand? I was pretty happy with it and then they put a glaze on my hair to dim the highlights and I think that was a mistake. I chose the less strong version because I wanted to loose frizz but be curly. Curious who has had one and what brand it was if you liked your curls (not looking to be straight) after.
