Where these two actually differ
- We flag Surfactant irritation (skin/eye contact) and Microbial contamination (post-purchase) on the Aveeno and not on the Rahua.
- We flag 1,4-dioxane (surfactant contaminant), Formaldehyde releasers (preservative allergens) and Mechanical irritation from exfoliant particles on the Rahua and not on the Aveeno.
- Both carry a flag for Fragrance allergens, so neither choice avoids it.
- The Aveeno is aqueous liquid shampoo (typical surfactants, conditioning agents, water) where the Rahua is Water-based shampoo (aqueous surfactant blend), 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 →
