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 Bumble and bumble.
  • We flag 1,4-dioxane (contaminant from emulsifiers), Fragrance allergens and undisclosed components and Formaldehyde releasers in preservative systems on the Bumble and bumble and not on the Avalon Organics.
  • The Avalon Organics is Water, conditioning agents, organic plant extracts where the Bumble and bumble is aqueous conditioner with seaweed extract, which is most of the difference in these two grades.
