The final move of the Codex ritual. C12 combines caviar extract, sodium hyaluronate and green tea and larch extracts in a light serum that amplifies the mask's effect and leaves a glossy finish before rinsing. Applied to damp hair, it smooths the cuticle, restores slip and shine, and opens the fiber for everything that follows. No shortcuts.

★★★★★Verified buyerBleached

“After two bleachings my hair was straw. Three weeks of the Codex and my hairdresser asked what salon treatment I'd had. This.”

— Laura M.

The ritual — 40 seconds

The experience

Feel it before you decide

The texture

A drop that melts between warm palms — weightless, without film or grease. Hair stays hair, only softer.

The gesture

Three slow strokes, from lengths to ends. The comb closes the cuticle — you hear it more than you feel it.

The morning after

The first thing you notice is light: hair that reflects again. That is the moment the ritual becomes a habit.

If a product is truly good, it doesn't need to convince you — it needs to reach your hands.

Role in the ritual

Movement 04 — Finish. The serum closes the ritual: it amplifies the mask's effect and leaves a mirror finish — then rinses out after 10 minutes.

The Ritual

What to expect

First ritual

Instant slip, softness and reflective shine — the cuticle lies flat again.

Week 2

Ends stop catching and snapping when you comb; hair feels sealed.

Week 4

The fiber holds moisture on its own — less frizz, more fall.

Fine hair

“The serum alone is worth it — my ends stopped snapping off within days. The comb feels like jewellery.”

— Sophie K.

Thick hair

“I've tried every mask on the market. This is the first thing that changed the structure of my hair, not just the surface.”

Colored

“My color used to fade with every wash. Since the ritual it holds — and the shine reads as salon-fresh for days.”

— Mara J.

★★★★★

Curly

“Curls are drama. This is the first routine that didn't flatten them — it just made every spiral glossy and defined.”

— Nina R.

★★★★

Heat-styled

“I blow-dry daily. Week four: no more snapping when I comb, and the ends finally lie flat instead of fraying.”

— Amelie B.
