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 Kristin Ess.
- We flag 1,4-dioxane (synthetic byproduct), Formaldehyde releasers (preservative systems), Fragrance allergens (undisclosed ingredients) and Bacterial or mold contamination (post-purchase) on the Kristin Ess and not on the Aveeno.
- The Aveeno is aqueous liquid shampoo (typical surfactants, conditioning agents, water) where the Kristin Ess is aqueous shampoo base with peptides and surfactants, 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 →
