Why is red hair so special?

Specifically, redheads have a mutated melanocortin-1 receptor (MC1R) gene that produces an altered receptor for MSH. Melanocytes, the cells that produce pigment in skin and hair, use the MC1R to recognize and respond to MSH from the anterior pituitary gland.

Do redheads feel pain differently?

Summary: Humans and mice with red hair have a different tolerance for pain because their skin's pigment-producing cells lack the function of a certain receptor. Lack of this receptor function causes changes that tip the balance between pain sensitivity and pain tolerance.

Why do Surgeons Dread redheads?
