anyone tried brazilian keratin treatment?

[slynnenyc]

hi! i'm looking to hear any experiences y'all have had with the rejuvenol brazilian keratin treatment (formaldehyde-free version that stays in for 5 days) that everyone's raving about. my hair is thin, fine, frizzy and curly -- so i'm hoping it'll end my frizz without leaving me flattened and curl-less, but of course it's a risk, and expensive. any input appreciated!

They were different brands starting with Simply Straight, Marcia, and Coppola.
The first 2 worked great, Coppola was done 2 weeks ago and did NOT work. My hair stylist offered to re do the treatment but with Marcia.
My hair is coarse, wavy, dry & frizzes easily (Florida weather). The first 2 made my hair shiny, silky, manageable, no frizz even on the most humid days.. And the best part is you won't need any styling products, it also cuts your drying time by 50%. The treatment includes full sizes of special shampoo & conditioner, plus a bottle of serum to take home.
Simply Straight and Marcia had to be left in your hair the first 3 days, but it was no big deal. It looked just fine but you can't get your hair wet, or wear it in a pony tail or use headbands, pins, hats, NOTHING! If you do within those 3 days it will leave a bend, crease etc. The treatment lasts 3-4 months depending on how often you shampoo. If you want it to last you should shampoo less and just rinse your hair and use the conditioner that was given to you. Use NO other kind of products that contain sulfur.

Coppola brand left my hair dry, brittle, dull, frizzy and my hair was still wavy. I have to blow dry and use a flat iron to have it look good. So it didn't save me any time at all.
Google SimplyStraight and Marcia Keratin treatment for more info.

I cringed.

I've done this. I ordered it and did it myself for $100, the EXACT same thing that costs $300 and up in a salon (QOD Gold brand). I wasn't blown away by the results, yes my hair was shiny and healthier, but it was annoying not being able to wash it for four days.
