The art of dyeing or painting your hair is quite old. From the Egyptians and Greeks, who clung to cosmetics, they dyed their hair to darken it with henna and khol.
Later, the Romans joined this practice, achieving, apart from darkening, lightening the hair using a paste of beech wood ash. Mixing it with goat fat and incorporating lead salts helped darken the hair progressively. But it was a toxic ingredient.
At the time of the Renaissance, the tendency was to wear light hair. Because in Venice, people had a discoloration to lighter tones through natural soda and exposure to the sun.
However, in the 19th century, anilines and silver nitrate were used, which functioned as organic dyes. And it was in 1860 when nitrogen peroxide walked to the scene, which is what we know today as hydrogen peroxide. Ultimately offering a safe way to bleach hair.
Hair dyes, as we know them today, arrived in the 20th century at the hands of the French chemist Eugéne Schueller. A man who focused on the use of paraphenylenediamine as the main ingredient. Something that was a less toxic product than alcohol and ammonia. Always dedicating himself to the sale of his product to French hairdressers. He is the founder of the well-known company L’Oreal, starting it as a manufacturer of hair dyes.
