I have tried both of these several times (dropped them and returned to them) and I have gotten different results from them. I keep on hearing different results from members on the board too so I was thing I'll post mine here and see if others will follow..
And I also keep on seeing people asking what the difference is between these two.
The first time around I tried this was just when I had started CG and it wasn't enough to deal with my back then pretty oily scalp. I had to give it up.
I went back to it again here and at first it seemed very promising but then it just left my hair a big frizz ball.
(ETA: and really straw like feeling.) I always thought that this would be milder on my hair than the HCC but it doesn't seem to be.
It does seem to be less drying on the scalp some how..I don't get it.
It has one cleanser in it and it is supposed to only be 5%.
I first tried this after a couple of months on "full" CG and it seemed very drying on my scalp. Didn't leave my hair too dry or anything it seemed.
I used it again here when my hair got over conditioned and while it can leave my scalp a bit dry my hair always comes out really soft and non frizzy from it. Even if I use it twice (not common). I always thought that the HCC was "harsher" (pardon the strong word) than the Low-Poo but it doesn't seem like it with my hair anyways.
Has two cleansers in it.
ETA: I should add that my hair seems to go better with the Jessicurl products in general and the Devacurl products have slowly showed that they don't work well with my hair (except for Angell which I like).
ETA: Okay I can't spell...
