Hi everyone-

I am confused with all the QOD formula I'm hearing about, some of which I can't even find on keratin4u.com, and what the difference is between them all/which one works best for which types of hair. This is what I have so far:

QOD White
QOD Max Organic - form/aldehyde free
QOD Gold
QOD Max Original/Kerapremium?? - Where do I find this?

Is this all of them? Thank you for anyone who can give me more info!
