AI Technical Summary
Existing PPD-based hair dyes damage hair during the oxidation process and pose a potential carcinogenic risk. Furthermore, alternative products on the market, such as azo dyes, have insufficient color fastness, plant-derived ingredients have limited color options, metal salt hair dyes have cumulative toxicity, 5,6-dihydroxyindole molecules are easily oxidized leading to storage instability, and application process conditions are stringent.
This single-agent hydroxyindole hair care cream contains oligomeric hydroxyindole and 5,6-dihydroxyindole as a dyeing precursor. It utilizes glucose oxidase to catalyze the in-situ oxidation of glucose to produce hydrogen peroxide, creating a mild and continuous oxidative environment. This allows the dyeing precursor to form stable polymerized melanin inside and on the surface of the hair, avoiding damage to the hair caused by high concentrations of chemical oxidants.
It achieves high stability and one-dye effect, reduces hair dyeing time, enhances dyeing durability and natural shine, reduces adverse effects on human health and hair structure, and avoids uneven dyeing and damage.
