I went last night and bought 2 liters to see what all the fuss is about. It's a great deal considering it normally costs $28 for one liter. I have plenty of shampoo at home, so I bought the moisturizing conditioner and the color maintenance conditioner. I don't have color in my hair, but the color maintenance conditioner has silk protein in it. I haven't used these yet, but I'll keep you guys posted on the outcome. Kenra users- what were your results?
