Not everyone can have a great natural hair color, so we do what we can by coloring our tresses. As trends and culture evolve, our desire to alter the way we are perceived is an ever evolving mechanism. This is nothing new. The passion to alter our hair goes back to ancient times when the Egyptians used henna (flower), and the Romans tinted their hair blond using saffron flowers. During the 1800s, scientist William Henry Perkin accidentally made the first hair dye (he called it mauve) when creating synthesized quinine. It was a lot better than using henna as it lasted longer. The results revolutionized the textile industry and beauty industry. However, there is a cost to our health. Hair color has even more chemicals today and the European Union already banned over 100 of them. The banned chemicals could cause lung irritation, arthritis, cancer, and skin allergies. Here are 4 dangers of using hair dye and how it may affect your health.
