Apple Cider Vinegar Shampoo vs Nutritive Bain Satin Riche Shampoo 8.5 oz: which is safer?

Where these two actually differ

• We flag Surfactant irritation (skin/eye contact) and Microbial contamination (post-purchase) on the Aveeno and not on the Kerastase.
• We flag 1,4-dioxane contamination on the Kerastase and not on the Aveeno.
• Both carry a flag for Fragrance allergens, so neither choice avoids it.
• The Aveeno is aqueous liquid shampoo (typical surfactants, conditioning agents, water) where the Kerastase is aqueous shampoo base (water, surfactants, conditioning agents), which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
