How many milliliters of shampoo is bottled in a month?

250 ml. If you are in the south, you will use more, and there are fewer cold baths in the north, so you will use less. About 250ml bottles of shower gel and shampoo can be packaged separately for one month. It also depends on the concentration of shampoo, the durability of the product and the frequency of shampoo, as well as the length and quantity of hair.
