Hair coloring has become a fashion choice for people.

But the main harmful ingredients are: p-phenylenediamine, o-phenylenediamine, m-phenylenediamine, p-aminophenol, m-aminophenol, p-aminophenol, toluene, etc. Many people may know p-phenylenediamine, and many products also indicate "no p-phenylenediamine". In fact, other products such as m-phenylenediamine are also toxic substances in chemical hair dyes, so hair dyes do not contain chemical substances, and commercial deceit cannot be heard , must look at the ingredients.
