When I first saw the title of this post I thought "Yes!" but after reading the definition, I'm not so sure. My hair doesn't feel product-y after I wash (whether shampoo or co-wash), but when I detangle, no matter how careful I am, sometimes I can feel/hear my ends separating in a way that's distinctly different from when I rip through a tangle. So to me, that's sticky.
I'm glad you brought this up because I could not find info on this particular type of stickiness.
Hair Type: 4a/b
No HGs but Giovanni 50/50 conditioner and any sulfate-free shampoo are are working so far.
