I have always done modified CG since I started in Nov. I alternate lowpoos and nopoos. I haven't had an issue with scalp goo and my hair can look good for up to there days. Usually, by third day, I wash anyway to feel cleaner. I get clumps. I like my modified CG. I don't use cones, though lowpooing would remove them anyway.
Cones definitely give hair staying power and fight frizz, so they're popular, sure.
I figure water-soluble is still healthier and cowashing more often is gentler on hair. Can't cowash with cones.
