Where these two actually differ
- We flag Fragrance allergens, Heavy metals in plant-oil extracts and Silicone polymer accumulation (conditioning agents) on the Cantu and not on the Credo Beauty.
- We flag Fragrance allergens or undisclosed fragrance components and Mechanical irritation from crystal size and shape on the Credo Beauty and not on the Cantu.
- The Cantu is aqueous shampoo base, plant oils, polymers, emulsifiers where the Credo Beauty is salt crystals, mineral-based scrub, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Credo Beauty is the one to buy.
