Researchers believe redheads are more sensitive to pain because of a mutation in a gene that affects hair color. In people with brown, black and blond hair, the gene, for the melanocortin-1 receptor, produces melanin.But a mutation in the MC1R gene results in the production of a substance called pheomelanin that results in red hair and fair skin.The MC1R gene belongs to a family of receptors that include pain receptors in the brain, and as a result, a mutation in the gene appears to influence the bodyâs sensitivity to pain.he mutation in the MC1R gene also occurs in brunets, although itâs less common. In the latest study, the researchers tested for the MC1R gene variant, finding it in 65 of 67 redheads and in 20 of 77 people with brown or black hair.
