The technology's reconstructive biomolecules act on the hair cuticle to strengthen the hair, while Palmaria palmata's film-forming effects address split ends.
Furthermore, the inclusion of arginine aids in the boosting of hair fiber resistance from the inside out, reportedly increasing fiber diameter by 25%, an impact similar to keratin, per Provital.
The fiber strengthening specifically addresses impacts of stress factors and hormonal shifts, according to the supplier.
Densinaria is of 100% natural origin and is COSMOS-approved.
