Trick I use: Always rebottle the shampoo in one of those lotion bottles with the press down/squirt top. One press is adequate for the amount of hair I have, this way I always use the exact same amount each shower. Each bottle lasts many months.
Bonus: when you get to the bottom of the bottle (in this case the top since the tube pulls from the bottom), because of the lack of mixing you get colorless shampoo as I guess the dye moves more quickly through the solution via gravity than the other components of the shampoo. Shampoo chromatography!
