I'm considering trying this too as it keeps being advertised on my facebook.
I've got curly hair (ish) but mostly on the first day, just kind of frizzy/wavy after that, and none of the many curly products and systems I've tried have helped much.
I didn't ever feel my hair got clean with the curly girl co-wash type stuff, so I want a proper shampoo - would you suggest buying this one, or just going for the mousse and gel steps of this one (is that 4 and 5)? You can buy those separately, which might be better than spending on the whole kit when it might well not work for me.
And what do you do in the days in between the washing? Doesn't it look awful after sleeping on it - how can you get away without combing it through, as mine is wild and all over the place in the mornings? And even if I put a shower cap on it, the moisture from a shower will make it frizz.
Also, if you end up straigtening it/using a hot brush/curl secret/etc on it in the days in between, does that ruin whatever you're doing with the merwave system to get is used to that pattern?
I geenrally wash mine at night, put it in a pony tail to make the top half of it straight, and then get waves at the bottom, which are OK, but end up a bit frizzy and ratty, so I was loooking for something that would make those waves much smoother and sleeker. I end up using hot brush or curl secret or straighteners on it in the end. This sounds like it would involve a lot of early mornings, which I am not so keen on...!
