I agree that trying to get the results on the package is more difficult now that it's a 4 oz and not a 5 oz tube for the same price. So I had this idea where I removed the cap of the empty tube, grabbed a different bottle of shampoo (I believe I paid about $3 for an 18 oz bottle) and I slowly squeezed the full bottle into the tube until it was full again. I expected it to come out the same color that went in (light green) but it came out jet black. I used it until it was all gone again and noticed that I was able to maintain the color I had. Not sure this will work for others, I feel I got more of my money's worth.
