I have red hair and when got my wisdom teeth removed, my father told me that they had to use more than the regular amount of anesthetics usually needed. At first, I thought nothing of it. Then, when I later started a research paper on red hair, I found out that people with red hair generally need around 20% more anesthetics than people with other hair colors. Why is that? Is it because my MC1R gene is mutated, or is it something else completely.
