Is it true that people with red hair experience pain differently than people with other hair colors?

Yes. A comprehensive review reports that people with red hair often require higher anesthetic doses for the same pain relief, and a referenced summary of genetic studies describes reduced sensitivity to noxious stimuli and altered responses to cold, heat and lidocaine in redheads. A separate study links MC1R variants to greater dental pain fear, and another finds red-haired women less sensitive to capsaicin-induced hyperalgesia.
