You cannot compare the difference between having a pump on the shampoo bottle and when not. It is absolutely convenient and economical instead of pouring the shampoo freely where most of the product is wasted. Definitely get this along with your xxl size shampoo
I am already a fan of the kerastase products. I bought this Kerastase 1000ml Pump because the the price is cheaper when you buy a big bottle like this. I am very happy with it, I leave it at my bathtub. The pump works very well.
