Where these two actually differ
- We flag Heavy metals in plant-derived ingredients, Fragrance allergen or undisclosed sensitizers and Silicone or plastic microparticle buildup on hair on the Avalon Organics and not on the Dove.
- We flag 1,4-dioxane (manufacturing contaminant), Fragrance allergens (undisclosed components), Silicone accumulation on hair over time and Contact dermatitis or scalp irritation (individual sensitivity) on the Dove and not on the Avalon Organics.
- The Avalon Organics is Water, conditioning agents, organic plant extracts where the Dove is aqueous conditioning emulsion (silicones, humectants, emulsifiers), which is most of the difference in these two grades.
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 →
