For me as far as shampoo and conditioner goes, I can tell if it's moisturizing to my hair usually while I am rinsing it out. I have experienced a shampoo that left my hair feeling dry and brittle while it was wet! My hair was not soft at all, but, hard and a conditioner. They were Optimum Care Collagen Moisture Shampoo and LeKair Aloe Cholesterol (the green one) I immediately dumped the LeKair Aloe Cholesterol.
