I'm tempted to try this method since I've been getting skinnier clumps with MGA sculpting gel but I'm a bit wary about rinsing upside down in the shower. I've tried it once before a while back and just got water up my nose.
Are you guys doing this in a bathtub or in a shower with a hand showerhead? I have a rain showerhead much like this http://www.chinashowerrooms.com/Show...hower-Head.jpg
so it's not as user friendly for upside down rinsing.
