NIFEISHI · Rosemary Mint Scalp Hair Strengthening Oil
Three independent Greenlens lenses read the same 28 ingredients and land 83 points apart. That gap is not an error. Each lens asks a different question, and this page shows every answer, ingredient by ingredient, blended into nothing.
Our sources have reference data on 22 of 28 listed ingredients; 6 are uncharacterized in our data — a gap, not a clean bill. Our sources can only speak to ingredients they recognize — either flagged by an authority or known to be a common, well-characterized ingredient. An uncharacterized ingredient is a gap in our data, not a clean bill of health: a quiet safety scan over ingredients we can’t place is a weaker signal than one over ingredients we can.
Uncharacterized in our data: Euphorbia Avena (Horsetail) Extract, Aloe Barbadensis (Aloe Lavandula Angustifolia (Lavender) Oil, Herb Extract, Ajuga Grayantsia (Bugleweed) Seed Extract, Petroselinum Crispum (Parsley) Oil, Satyja Officinalis (Sage).
Independent
The regulatory baseline. Follows EU cosmetic law: prohibited and restricted ingredients cost points, and allergen labelling is capped so it cannot tank a score on its own.
Flagged 4 of 28 ingredients: 1 prohibited, 3 regulated allergens. Score capped: a prohibited (banned) substance is present.
Independent
The strict lens. Flags any ingredient with a listed hazard trait (SIN List, IARC, Prop 65), even when regulators still permit it.
Flagged 1 of 28 ingredients on hazard grounds: 1 mild sensitizer.
Independent
The lenient lens. Trusts dose and regulation: permitted ingredients kept within their legal caps are tolerated, and only genuinely prohibited substances take a big hit.
Flagged 1 of 28 ingredients: 1 prohibited. Score capped: a prohibited (banned) substance cannot be tolerated.
These lenses disagree. A split of 83 points crosses our disagreement threshold (20). We keep every verdict and never average them; the table below is where the split comes from.
