Didn't work for me

I bought the shampoo, conditioner, and leave in treatment to see if I could give some life to my curls that I always thought were just frizzy waves my entire life. Unfortunately these products left my hair greasy and sad. I tried using the conditioner before the shampoo too, just to see if it would somehow help, but still the same greasiness. Usually I can go half a week without my hair getting to the greasiness level where I need to wash it again, but these products had my hair beyond that point in a day. I was really disappointed.
