I also struggle with this, mostly due to the length of my hair (BSL). In addition to layers, applying to soaking wet hair upside down & clipping, I find that plopping helps counter the effect of gravity that christina.gr mentioned.
You might want to try shampoo bars. Nothing else gives me spirals like they do - think DNA double helix! I prefer Chagrin Valley, but there are several other manufacturers that produce sulfate-free poo bars.
