I have been using this product for over 10 years. Until recently, one bottle was adequate. Now, I get about 3/4 through the process, and I run out of dye. (And I am only concentrating on my roots!) I thought maybe I was doing something wrong, but when reading other reviews, it sure seems the bottle has less dye. So today, I had to buy two packages for one session. If you did decrease the amount, PLEASE go back to the amount it was! Also, please give us back the old conditioner... the one in the clear/orange tube. I was able to use it all month long and loved it! The root touch-up packet is terrible.
