The house
We formulate the way perfumers do — slowly, in small volume, refusing anything that does not earn its place in the bottle.
To translate the quiet intelligence of plants into rituals that restore hair to its natural brilliance — slowly, honestly, and without compromise.

Science behind the formula
Every active is dosed at the concentration used in the study we cite — not a trace amount for the label. Panel results are published in full, including the participants for whom nothing changed.
Twelve weeks
A 120-person panel used the Racine protocol nightly for twelve weeks. Density was measured by phototrichogram, not by asking people how they felt.


“The only line I have brought into the studio and never swapped out. It behaves the same on every hair type I put it near.”
Odile Ferrand
Editorial Stylist, Paris
“Aureum reads like skincare and performs like a treatment. That combination is genuinely rare.”
Dr. Hana Okonjo
Trichologist
“Three campaigns, forty models, zero complaints. It photographs beautifully under hard light.”
