| Research has shown that people with red hair perceive pain differently than others. They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher. People with red hair also respond more effectively to opioid pain medications, requiring lower doses. |
