I treated it like a conditioner, after shampoo, (no poo) not a DT. I did it like that 2 days in a row (no shampoo the 2nd day) and by yesterday my curls vanished. No other products were added. I have not touched my hair sense letting it just "chill" out. Yesterday morning I ran all over town returning products I've gotten and did work. I understand how you feel! My hair doesn't really like oils either. They weigh it down. Wish I had better news for you, I know you went through trouble to get this!!
