At this point my hair is more soaked than it would normally be when I step out of the shower, so it is kind of drippy. I scrunch in my gel of choice and plop. I guess you could towel scrunch, instead. I don't plop long (5 - 10 minutes), but that's just me. Then, I either air-dry for a few and then diffuse or diffuse straight away.
I find that the base coat I use affects my success. Please remember that I have A LOT of hair and can afford to uber-clump; this might overly clump those looking for volume.
The best base coats for me are those that provide light emollience. I have tried NO basecoat, I have tried heavy (I.E. butters), I have tried my gel as a base coat. While my hair WILL initially clump upon soaking with those, these clumps break up by or before drying, resulting in frizz of stringy/broken up curls. My greatest success has come with basecoats that are creamy yet light (think CJSG or CJCCC).
For those who find their hair gets so wet that it increases drying time: I have played with a double plop with great success. I saturated my hair excessively (after CJCCC) and then went into a plop without scrunching in gel (thereby not squeezing out a DOT of water). I plopped for 5 minutes then came out, got a dry Curlease and went into a plop again. Plopped for another 5 then came out; my hair was no worse for the wear and much drier. My next trial will be applying a gel between plops.
I have found that certain areas of my hair, like the underside, that have always tended to clump on their own and can get overly clumpy with this method. I avoid this by gently running my hands thru those few areas before I diffuse (while still wet!) But the best part is that I am getting consistent canopy clumps which I have never had before!
My kids call this the "Super Soaker" because they are dying for me to let them do it to my hair with their water guns.
I hope this was semi-clear. And I hope this helps someone!
