TLDR Nanoparticles could make hair dyes safer by reducing harmful effects.
The document discussed the use of nanoparticles in hair dyes, highlighting that traditional hair dye chemicals such as ammonia, peroxide, and p-phenylenediamine (PPD) were effective for permanent hair coloring but often caused adverse effects like skin rashes, itching, hair loss, dandruff, irritation, cancer, asthma, allergic responses, and weakened eyesight. It suggested that nanoarchitectonic approaches could mitigate these unwanted properties, potentially offering a safer alternative for hair dye formulations.
