Problems solved by technology

Especially for the elderly, it is easier to choose hair dyeing in order to retain a youthful appearance. There are mainly three types of permanent hair dyes that do not fade on the market: plant-based, metal-based and oxidized. Among them, plant-based hair dyes are used from The substances extracted from the stems and leaves of plants are used for dyeing, which is expensive and rarely used in China
Oxidative hair dyes are currently the mainstream hair dyes on the market, but most of them contain p-phenylenediamine, which is a known carcinogen, and p-phenylenediamine is a high allergen. In direct contact with the scalp, people with allergies are prone to allergies
The use of these hair dyes causes allergies and even infections, and contains carcinogens that are harmful to health
