Where these two actually differ

  • We flag Heavy metals in botanical extracts, Fragrance allergens and sensitizers and 1,4-dioxane contamination on the Mielle Organics and not on the Avalon Organics.
  • The Avalon Organics is Water, conditioning agents, organic plant extracts where the Mielle Organics is aqueous conditioner base; botanical extracts (rosemary, mint), which is most of the difference in these two grades.
