LOL funny you should mention this, I seen this today at Walmart for $5 and that thang is HUGE! But I hadn't seen any reviews on it, but I'm considering purchasing it soon, just to try it out. But thought I'd see what was on the board about it first before doing so. I'm in love with the HH condish, but just wasn't sure about this combo thingie!
I've used a 2 n 1 before, but I used it like a regular shampoo and DC'd after. I think the 2 n 1 HH is better than using a regular sulfate shampoo. JMO
