SCIENTIFIC DISCOVERY

Why is metal dangerous for your hair?

Every day, hair absorbs metal. Hair stressors (sun / UV over-exposure, overprocessing, intense heat, salt & chlorine water, high porosity) accelerate metal accumulation, leading to an over-concentration of metals within the fiber.

Hair becomes increasingly dry, brittle and prone to breakage, in urgent need of rescue.

    • Locks in 1000 hours of deep hydration
    • The Glicoamine technology helps to restore the hair's natural moisture balance.

  • 6. What product can help my hair recover from the harshness of overprocessing and bleaching?
