How we work it out
Each price is the one the maker’s own store charges for that size, read between and (each product page gives its own day). We divide it by the size the maker prints. Shop and Amazon prices aren’t used, and a markdown is shown as one.
A size in fluid ounces or milliliters is priced per fluid ounce. Some makers print just “oz” without saying whether it means fluid ounces or weight, and those are priced per “oz” as printed, so treat a gap of a few cents between the two as a tie. A price per ounce isn’t the price of a wash: how far an ounce goes depends on how much you use, so the cost-per-wash link on each line works that out from your own amount.
64 of the products we compare aren’t here because their maker sells only through other shops, or its store gave us no price for the sizes we list. Where a store priced only some sizes, the line shows those. Their pages still give every size and the maker’s directions.
Download every size and price as a spreadsheet (CSV)
The download lists every size we compare, priced or not, with the day each price was read and the maker’s store page, so you can check any line. A blank price means the store gave us none. A size the maker prints as plain “oz” is marked that way and priced per “oz” as printed, never counted as fluid ounces.
