I use it! About half the time when I low poo with coco-betaine, or clarify. Sometimes I do it as a pre-poo, and put conditioner (and/or some oil) on my dry hair (sometimes I mix the condish with a little water first, or spritz my ends lightly), leave it for 5-10 mins, then shower and poo it out.
Regardless of method, I almost always poo just my scalp, then just rinse the through the rest of my hair. I only ever poo all my hair if I really need to clarify for some reason (build-up, bad ingredient that doesn't agree with my hair, etc.)
