Kava Kava Hyalurogen Serum restores hair structure through a meticulous combination of hyaluronic acid and natural collagen, without added harmful salts. Especially for dry, colored, or damaged hair, it penetrates deep into the cortex and returns lost moisture and strength to the hair. The result: soft hair with a natural shine and silky touch. Usage is simple: dispense 2-3 pumps onto your palm, starting from the ends and continuing along the lengths on damp or dry hair, gently brush, and finally smooth with your hands. For optimal results, complete with the Hyalurogen Mask from the same series.
