The weight of the plastic from the bigger 24 ounce plastic bottle with a spout/dispenser is going to be more than 24 times the weight of the little single use bottle that holds 1 ounce of shampoo, due to the greater thickness of the larger bottle as well as the thick plastic spout/dispenser which is not present in the little bottles.
Again this not only has nothing to do with the environment but it actually has the opposite effect on the environment. People have been duped so badly on this.

while I agree that the main driver is cost saving it doesn't take away environmental benefits - larger bottles are easier to recycle and they use less plastic.
For the sake of simplicity
imagine a cube 10x10x10 cm with 1l capacity - total surface area 600 sq cm
imagine 1000 small cubes 1x1x1 of 1 ml capacity - total surface area 6000 sq cm
10 fold difference of surface area partially offset by thickness. Then you have 1000 small caps vs 1 large pump piece.
Obviously shapes and actual sizes will vary but the trend is the same.
