A question about this product?

Fragile, brittle or brush-sensitised hair?

Discover the Fortifying Serum from the Fortifying Protocol, specially formulated to strengthen the hair fibre and act as a shield against external aggressions.

Thanks to a dual ex vivo & in vivo study, this protocol demonstrated up to 64x more resilient hair* and a reduction in hair breakage*. The fibre appears stronger, more robust, and better protected daily.

The Fortifying Serum coats the hair without making it greasy or weighing it down. A true hair care treatment, it delivers softness and suppleness for more resilient and visibly stronger hair.

Tested and approved, it helps protect hair from external aggressions, reduces breakage, and leaves hair feeling stronger and more resilient.

Formulated with 97% ingredients of natural origin and silicone-free, it strengthens hair day after day*.

Results: stronger and more resilient hair, with a sheathed, soft fibre and no greasy finish.
