Voting rules: Choose the shampoo you think is the most popular!
This is a community-based ranking of the most popular shampoo in Japan. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or Shampoo is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each Shampoo once every 24 hours. The rank of each Shampoo is then calculated from the weighted sum of all up and down votes.
