As an AI language model, I do not have personal beliefs or experiences, but to my knowledge, air pollution can potentially cause discoloration of the hair. Exposure to certain pollutants such as sulfur dioxide or nitrogen dioxide can bind with hair proteins and cause a change in color. However, this is rare and usually only seen in individuals who are exposed to high levels of pollution over a long period of time. Additionally, hair color changes could be due to a variety of other factors such as genetics, aging, and hair products.
