Where these two actually differ
- We flag Surfactant irritation (skin/eye contact) and Microbial contamination (post-purchase) on the Aveeno and not on the Avalon Organics.
- Both carry a flag for Fragrance allergens, so neither choice avoids it.
- The Avalon Organics is Water, botanical extracts, conditioning agents where the Aveeno is aqueous liquid shampoo (typical surfactants, conditioning agents, water), 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 →
