My daughter had some when I went to stay. I loved how it made my hair soft, no fly a ways, and yet it wasn't greasy. I normally don't spend this much on hair/beauty products but this is totally worth it.
I've never used the extra strength conditioning rinse, so I can't compare the two. All I know is that as a swimmer (I try to swim 4x a week for about 2 hours), my hair gets dried out. This shampoo and conditioner is my lifesaver. And my scalp does NOT react to either.
I'm not familiar with the conditioning rinse but I can say that you won't be disappointed with the Amino Acid Conditioner. It has a pleasant smell and results in my hair being pretty manageable. I like it.
Best Answer:Danielle, between the two of us, my wife and I have way too many allergies - indoor and outdoor. We both use the amino acid shampoo and conditioner with no problem and really enjoy them. Good luck!
