POLYDIHYDROXYINDOLE

Description

Polydihydroxyindole is a synthetic polymer derived from dihydroxyindole, a compound naturally found in melanin. This innovative ingredient has gained attention in the haircare industry for its potential to mimic and enhance natural hair pigmentation processes. As a large molecule, polydihydroxyindole does not penetrate the hair shaft but instead forms a protective film on the hair surface.

The polymer's unique structure allows it to adhere strongly to the hair cuticle, providing a long-lasting effect that can withstand multiple washes. When incorporated into hair dye formulations, polydihydroxyindole can enhance color depth and longevity, particularly in darker shades. It also exhibits antioxidant properties, which may help protect hair from environmental stressors and oxidative damage.

In addition to its coloring properties, polydihydroxyindole has been shown to improve hair texture and manageability. It can help reduce frizz and increase shine, resulting in a smoother, more polished appearance. While research is ongoing, preliminary studies suggest that polydihydroxyindole may also have a mild strengthening effect on hair fibers, potentially reducing breakage and improving overall hair health.
