In just one box of L' Oreal hair color (Superior Preference True Brunettes #63 Ultra Light Gold Brown) 5 of these chemicals were used: P-Phenylenediamine, Ceteareth-30, Eugenol, Fragrance, and Resorcinol. Overall, the hair color had a high hazard rating on the Skin Deep database (score 10 out of 10). The hazards of the product are broken down as follows:

As a result of using P-phenylenediamine, hair color allergies are on the rise. People with severe reactions to the chemical develop rashes around the hair line and facial swelling, sometimes so severe hospitalization is required. Some hair colors use phthalates, dangerous chemicals that cause genital abnormalities in baby boys when mothers are exposed to them during pregnancy. Hair colors that use coal tar derivatives are linked to bladder cancer in women who use the colors frequently, as well as stylists who work with them frequently.
