I don't think it's either under or over conditioning. I think it's product buildup!
Sounds to me like your shampoo's not enough to get out the wax buildup. Since I gave up on trying CG and have been using Jessicurl cleanser, my hair is totally un-frizzy, and I think it's because the small doses of cones and proteins my hair was getting were making it frizz.
The pews never miss a sermon but that doesn't get them one step closer to Heaven.
But at least the pews never attend yoga!
