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 Formaldehyde releasers (preservative class), Fragrance allergen sensitivity, Microbial growth if unmaintained and Heavy metals in botanical extracts 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 conditioner; key actives are rice amino acids and shea butter, which is most of the difference in these two grades.
