I'm relaxed & texlaxed and I just bought the AOHSR (the smell is so loud to me) I like the results. I got it at Vitamin Shoppe for $7 and some change. Its my co-wash. I haven't tried to use it as a leave in.
I've never tried Trader Joe's, but I had to say that AOWC is the BOMB!!! I use that stuff for everything; cowash, DC, leave-in! It's all purpose if you ask me! If I could only get rid of the smell.....If I could have WC smell like HSR then that would be the best of all worlds!
Just co-washed with the NS and unfortunately, I was not impressed. It was thicker than Vo5 but it performed basically the same. It detangled my hair fairly well (finger detangling) so it's ok as a co-wash but it didn't have nearly as much slip as AOHSR so I know this won't be able to replace my AOHSR.
So I won't repurchase because Vo5 is 77 cents but I will use it up because it is a pretty decent conditioner.
