I know a lot of people don't like this one but DevaCurl Heaven in Hair is the heaviest conditioner I have ever used. I tend to be heavy handed with conditioners and I prefer very creamy/heavy conditioners in general. However, I had to be sparing with the Heaven in Hair when I used it because it would leave me over moisturized (something previously believed to be impossible).
