Sourcing note: two independent groups of sources give slightly different full ingredient lists for products with near-identical names to this SKU. This listing includes only the ingredients that are confirmed consistently across BOTH sources -- Hydrolyzed Keratin, Marula Seed Oil, Argan Kernel Oil, and several conditioning/emulsifying ingredients -- while a few additional minor ingredients found in only one list are not claimed here.
Key Ingredients
- Hydrolyzed Keratin -- a Keratin protein hydrolysate (broken down into smaller peptides), not intact/whole Keratin protein; included to help condition and smooth the hair surface
- Sclerocarya Birrea (Marula) Seed Oil -- a lightweight oil included to help add shine and softness
- Argania Spinosa (Argan) Kernel Oil -- an emollient oil included to help nourish and smooth hair
- Cetearyl Alcohol -- a fatty alcohol conditioning agent (not a drying alcohol)
- Dimethicone and Amodimethicone -- silicone conditioning agents that help reduce frizz and add slip
- Also contains Behentrimonium Chloride, Cetrimonium Chloride, Dipropylene Glycol, and Lactic Acid, per the ingredients confirmed across independent sources

Is the "72 hours of frizz control" claim independently verified?
