A. Dickey of Hair Rules Salon suggested that I use Neem oil at night and wash out in the a.m. because I had told him that sealing with oil didn't work for me. Neem is some kind of oil from India (I think) - very light. It is in Beautiful Curls Shea Butter and Neem Oil Nourishing Curl
oil. I expect most light oils would work fine.

I don't use heat. I'm pleased with the results when I use the Neem but BringingBack is right - oil will emulsify oil, so her method sounds very good, too.

Sometimes try roller sets or use a curling brush - classic glamor.
