This is a hair product. We read the same ingredient groups as on a skincare product — fragrance, sulfates, silicones and drying alcohols — but we publish no acne-prone rating and no judgment about whose hair or scalp it suits. An ingredient list cannot tell you that.
Confidence: medium · v2026.09.3
This assessment is read from the ingredient list and is not medical advice. It makes no promise about acne. Individual skin reactions vary.
Read how we classify productsDryingness 0/100 — practically non-drying. The reading comes from the ingredient list and its order, not from a measurement. The largest additions: Sodium Chloride (position 23). Pulling the score down: Sodium Methyl Cocoyl Taurate (position 4), Cocamidopropyl Betaine (position 7), Glycerin (position 11).
Computed from the ingredient list · v2026.08.1
The number is computed from the declared ingredient list and its order. A label does not state concentrations, so this is a reading of the formula — not a prediction of how the product feels in use.
How the dryingness index is calculatedThe order is the manufacturer's own and follows concentration down to the one percent mark. Underlined names are flagged by our criteria. Names with a dotted underline open a short note on what the ingredient does in the formula.
