Biotin B-Complex Thickening Conditioner vs Hydrating Conditioner: which is safer?

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 Verb.
• We flag Fragrance allergens, 1,4-dioxane contamination (trace), Preservative contact sensitization and Package leachables (if plastic bottle) on the Verb and not on the Avalon Organics.
• The Avalon Organics is Water, conditioning agents, organic plant extracts where the Verb is Water-based conditioner; typical cosmetic formulation, which is most of the difference in these two grades.
