this is normal so I wouldn't worry. The first couple of times after getting my hair dyed dark this happened to me too. It seems like soo much of it going down the drain and you're right you almost feel ripped off but it doesn't really affect your colour. I do the same as you and wait as long as I can before washing it after the colour. Another thing I have heard is not to use really hot water to have it on the colder side because hot water will make it come out faster as well. I looove the colour of your hair in your pics you just posted it looks really nice. Mine is on the blonder side right now.
