47 unique
Where The Ordinary Buffet really shines is active ingredient strength, scoring 8.4 compared to Trader Joe's Hair Serum's 2.1. Its formula features Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, and Allantoin in high positions, signalling meaningful concentrations.
Hydration Efficacy is another area of separation. The Ordinary Buffet scores 8.7 here versus 5.1 for Trader Joe's Hair Serum. That difference comes down to how each formula is built — the ingredient list tells the story.
The Ordinary Buffet brings Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, and Allantoin as actives, while trader Joe's Hair Serum relies on Rubus Fruticosus (Blackberry) Fruit Extract, Euterpe Oleracea (Acai) Fruit Extract, and Helianthus Annuus (Sunflower) Seed Extract. Both approaches have merit, but the positioning and supporting ingredients make the difference.
