RCC, thanks for the thorough review. I think I'll try this. I finished my Nexxus Emergencee and since I'm tolerating protein better these days too, this may be a good thing. I'm also prudently using cones as well.
It's a regular conditioner right, since you use it every time? I think rather than protein sensitivity last year, I experienced a protein overload. If I recall it happened after I had used Sebastian Penetraitt twice, and then tried Magic Botanicals conditioner which had keratin. I think a combination in those 2 were the tipping point.
I think the amount of protein is also key. I use Robert Craig, Mop Top, Loma, etc. and they all have some protein content, but not as a first 5 ingredient.
BTW you look like a goddess with that hair down your back!
