Okay--still battling this problem!! I used Suave as a leave in and it was really frizzy. Lately, I've just been rinsing all the conditioner (still TN) out and not doing a leave in. It is a little better that way.
I've discovered I only get the crown frizz and wet frizz when I apply products soaking wet. If I scrunch out the water with a towel, then apply product, I don't get the crown, flyaway frizz. BUT, it looks stringy and I have no clumps.
I like the way my hair looks when I apply product to soaking hair, so I want to make it work! I either need a different RO suggestion or I need a cream/pomade suggestion to calm the crown frizz after I SOTC. I bought JCNS, but it isn't doing anything for the crown/root frizz...
