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 Moroccanoil.
  • We flag Fragrance allergens (undisclosed components) and Eye irritation from silicone or surfactant residue on the Moroccanoil and not on the Avalon Organics.
  • The Avalon Organics is Water, conditioning agents, organic plant extracts where the Moroccanoil is aqueous conditioner with argan oil and silicones, which is most of the difference in these two grades.
