5 Stars, but 10 if I could do it! 
I got this in exchange for the Sap Moss shampoo and conditioner I bought. The Aveda stylist talked me into buying it saying how much she loved it, blah, blah. Okay, MAYBE I'll like it. I could always return it if it's whack.
Well, this conditioner is FABULOUS!!

Very, very moisturizing and detangles beautifully. It felt like I could detangle with my fingers! I liked it so much that I left some in as a leave-in. It's supposed to smooth the hair and eliminate frizz. I guess it does, but I don't know for sure. I didn't use it by itself and followed up with a gel.
UPDATED 12/24/07: I had to change my rating to a ONE, because there is something "off" about this conditioner. I used it for the second time a few days ago and my hair wasn't looking right. I'm having a hard time explaining it properly, but my hair (especially near the ends) was taking on a "cottonball" or "matted" appearance. No, it wasn't matted, but it wasn't looking normal either. I had to rewash my hair to make sure the conditioner was out and used something else. Thankfully, it worked.
This worked fine the first time I used it, but I think with continued use it will mess with the hair "texture" in some way. It could be my imagination, but I'm not taking anymore chances.
