This shampoo is tricky. I've seen many people are complaining about their hair being very greesy after washing with this shampoo. It happened to me too when I used it first time. I washed my hair in a sink that time and didn't rinse well. That's the reason this shampoo leaves your hair greesy. You have to rinse your hair all the way. After rinse if you touch top of your head and rub it, if bubbles start forming, it means you did not rinse it well. If you rinse your hair properly this shampoo doesn't leave your hair greesy at all. I've used it for a few months but I didn't feel much difference with my hair. My hair still feels really dry, especially the ends. Maybe this shampoo works better for you. I used different conditioner because I never found Reconstruct conditioner.
