Itchy Eyes- I have had grit in my left eye for quite a few years. It is very uncomfortable. I finally figured out what caused it. I was using shampoo -- the Walmart version of Head and Shoulders. After I stopped using it, this condition went away. My dermatologists had recommended I wash my face with my shampoo. I am 10 days from using it and my eye has been completely healed. By not using it any longer, my face is not as red either.
