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 Garnier Fructis.
  • We flag Fragrance allergens and sensitizers, Preservative irritation (methylchloroisothiazolinone/methylisothiazolinone), 1,4-dioxane (contaminant in ethoxylated surfactants) and Silicone accumulation on scalp over time on the Garnier Fructis and not on the Avalon Organics.
  • The Avalon Organics is Water, conditioning agents, organic plant extracts where the Garnier Fructis is aqueous conditioning liquid (silicones, botanical extracts, surfactants), 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 →
