How we determined rating score for R+Co BLEU Shampoo

We strongly believe that the best information about a shampoo's performance comes from actual users. This includes details like how well it works for different hair types, health benefits, look and feel, and any side effects. Our analysis and scoring method includes:
  • Using AI to collect shampoo reviews from major online stores. We analyze these reviews to find out what customers care about the most, like how the shampoo works for different hair types, its scent, and its effectiveness in treating scalp and hair issues such as dryness, flakiness, or oiliness. We also look at other factors like how well it moisturizes, adds shine, and affects hair tangling.
  • Once we identify the main topics customers talk about, which we call product attributes, we use special AI algorithms to track every mention of these attributes in each shampoo we study.
  • For each shampoo and attribute, we calculate several metrics, like how often it's mentioned, its percentage of all reviews, and the balance of positive and negative feedback. We then compare these numbers across different shampoos to create a comparative score for each one, done separately for every attribute.
