Where these two actually differ
- We flag Surfactant irritation (skin/eye contact), Fragrance allergens and Microbial contamination (post-purchase) on the Aveeno and not on the Ouai.
- We flag Fragrance allergens and undisclosed fragrance components, Preservative-induced contact irritation and Scalp or eye irritation from surfactant concentration on the Ouai and not on the Aveeno.
- The Aveeno is aqueous liquid shampoo (typical surfactants, conditioning agents, water) where the Ouai is shampoo and conditioner (aqueous cosmetic formulation), which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
