L'Alga Hair Care

The North Atlantic coast of France.

Five species of algae, hand-harvested using traditional methods that have existed for generations. No mechanical stripping. No GMO intervention. No shortcuts.

This is how AlgaNord5 begins, not in a lab, but in the ocean. The lab is where we learn to harness what the ocean already knows.

Sustainable luxury isn’t a positioning statement. For L’Alga, it’s the only way the product can exist.

Available in 34+ countries. Formulated without compromise.

SEALUSH isn’t a styling product. It’s a decision.

Split end prevention. Heat protection. Gloss without weight.

One serum that earns its place in the routine, not as an extra step, but as the step that makes everything else work better.

The ocean doesn’t rush. Neither does good hair.

Save this if you’ve been looking for a serum that actually does what it says.

Most masks treat the hair.

SEACURE treats the system.

Biotin. Niacinamide. AlgaNord5 Bio-complex. Applied to the scalp and lengths, left for 5 minutes, rinsed with results that compound with every use.

This is what long-term hair health looks like, not a one off. A protocol.

Split ends don’t just live at the ends.

When hair has been repeatedly lifted, heat-styled and exposed to hard water over years, the damage runs through the mid-shaft. No amount of conditioning will fix a broken protein bond.

SEAMOLECULAR CPR works at the peptide level. Peptide-18 targets the sites where bonds have broken, restoring structural integrity from the inside rather than coating the surface.

The result isn’t just visible. It’s measurable.

Chemically treated. Coloured. Dry.
This is where most “treatments” fail.

Enter CPR 🌊

Powered by marine bio-technology and the AlgaNord5™ complex, this isn’t surface-level shine, it’s deep repair from within the hair fibre. Peptides, keratin and ocean-derived actives work to rebuild, strengthen and restore compromised hair instantly.

The result?
Stronger. Softer. Smoother. Healthier-looking hair after just one use.

No heaviness. No masking damage.
Just real recovery, and visible shine you can’t fake.

If your hair has been pushed to its limit… this is how you bring it back.

Luxury in haircare isn’t about hype. It’s about what’s inside.

L’Alga Haircare was built on a simple idea: the most powerful ingredients for hair might come from the ocean, not the land.

At the heart of every formula is sea algae, a resilient marine ingredient rich in amino acids, minerals, and antioxidants. Designed by nature to survive extreme conditions, it helps strengthen, protect, and restore the hair fibre.

But what makes it luxury isn’t just the ingredient.
It’s the precision behind it.

High-performance formulas. No unnecessary fillers. Just advanced science combined with carefully selected marine actives that deliver real, visible results.

This is haircare, redefined.
Powered by the ocean. Refined by science.

Shine, softness and an irresistible fragrance.

Seascent leaves your hair feeling and smelling fresh all day.
