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 Briogeo.
  • We flag Fragrance allergens and botanicals, 1,4-dioxane contamination and Microbial growth if contaminated during use on the Briogeo and not on the Avalon Organics.
  • The Avalon Organics is Water, conditioning agents, organic plant extracts where the Briogeo is Water-based conditioning cream; standard cosmetic emulsion, which is most of the difference in these two grades.
