I like the Just for me oil moisturizing lotion, but I have never used any type of grease. I can reapply the lotion daily and it doesn't make her hair crunchy (which I HATE) Her hair is usually in rubberbands to prevent tangles, but I can reapply the lotion to the hair everyday and make it look fresh if I don't have time to re-do it. I usually have to do her hair every 4 days, but I only wash it every other time and just condition it on days I don't wash.
I use johnson's conditioning shampoo and conditioner in one (blue bottle - see link below) once a week and the silken child conditioner twice a week. I apply the oil moisturizing lotion at least every other day. Everyone's hair is different though so that is what I use.
