Apple Cider Vinegar Shampoo vs Acidic Bonding Concentrate Shampoo & Conditioner Set - 1 l / 33.8 fl oz: which is safer?

Where these two actually differ

• We flag Surfactant irritation (skin/eye contact), Fragrance allergens and Microbial contamination (post-purchase) on the Aveeno and not on the Redken.
• We flag 1,4-dioxane (synthesis byproduct in ethoxylated ingredients), Fragrance allergens and undisclosed fragrance components, Formaldehyde releasers (preservative system) and Scalp irritation from alkaline buildup if rinsed inadequately on the Redken and not on the Aveeno.
• The Aveeno is aqueous liquid shampoo (typical surfactants, conditioning agents, water) where the Redken is aqueous shampoo and conditioner formulations, 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.
