twwirly -- sorry for the late reply. i think you and i might have really similar hair based on your other posts, so here goes ...
i'd say spin control is somewhere in between a leave-in and a styler, in the sense that its texture is very similar to Abba nourishing. it's marketed as a leave-in styler (don't have exact quote), although i can't vouch for any real moisturizing properties other than 'cones, if you want to count those as moisturizing. i've been doing a LOT of experimenting lately with various cream stylers. spin control is the only product that gives me clumping, separation, and decent hold with absolutely zero crunch or residue. it's funny because i used to despise spin control in the past -- i think i just wasn't using enough. i feel like no matter how much i put in, it never feels gross in my hair. i've tried a couple other things lately that give me a similar look but my hair feels dry with those; with spin control, my hair always feels extremely soft. maybe the one downside to spin control is that it doesn't really help with volume. it doesn't have the same type of "tense"/soft hold that, say, rusk wired does (you are familiar with that, right?) i think spin control might be perfect with just a hint of gel on top (though gel always turns my hair into a giant mess).
i feel so-so about the rusk jele gloss; i can't ever tell if it's really doing anything for my hair. i think, if anything, it's good for volume if that's what i'm going for.
my shampoo does not have sulfates, but does have other detergents. i'm really happy with it. my conditioner's formula changed and now i'm on the hunt for a new one.
keep me posted on your hair experiments!!
