I have fine, thick, wavy hair too. It was long until about a month ago but now it's in a bob as I'm growing out to my natural color.

I often do the rinse only thing and then follow with a spray-in conditioner.

Something I haven't tried lately, but we all used to do years ago, was use baby powder. Sprinkle it on, brush it out. Seems to take all the icky stuff with it.

I may try it again next time.
