My ends are definitely lighter than the roots, I've only recently decided to start shunning the sun more so I'm sure that's why.
My hair doesn't slip easily when I run my finger up it as jsuzkelly suggested, but it didn't feel super bumpy and "catch" either. It was more of a squeaky resistance feeling. Maybe a couple little bumps. So I'm guessing this means it's middle of the road porosity? Oh and drying time... mine dries (depending on the weather of course) in a few hours - 4 at max. Usually more like 2-3. Sometimes less. LOL
