Despite their vibrant locks, redheads make up just 1-2% of the world’s population, making them a unique genetic group. Here are five fascinating facts about red hair humans:
1. The Redhead Gene
Red hair is caused by a mutation in the MC1R gene, which controls the production of melanin, the pigment that gives our hair, skin, and eyes their color. This mutation results in the production of a reddish pigment called pheomelanin instead of the brown-black eumelanin.
2. Redheads Experience More Pain
Studies have shown that redheads have a higher sensitivity to pain than people with other hair colors. This is due to a difference in how their bodies process pain signals.
3. Vitamin D Deficiency
Redheads have a higher risk of vitamin D deficiency. Vitamin D is absorbed through the skin when exposed to sunlight, and the pale skin and red hair of redheads make it harder for them to absorb sufficient amounts.
4. Redheads Have Unique Hair Characteristics
Red hair is generally thicker, curlier, and more resistant to damage than other hair colors. This is due to a higher concentration of a protein called trichosiderin.
5. Redheads and Cancer
Research suggests that redheads may have an increased risk of certain types of cancer, including melanoma, skin cancer, and prostate cancer. However, the exact reasons for this increased risk are still not fully understood.
| Trait | Redheads | Non-Redheads |
|---|---|---|
| MC1R Gene | Mutated | Non-mutated |
| Melanin Production | Pheomelanin | Eumelanin |
| Pain Sensitivity | Higher | Lower |
| Vitamin D Absorption | Lower | Higher |
| Hair Thickness | Thicker | Thinner |
| Hair Curvature | Curlier | Straighter |
| Trichosiderin Concentration | Higher | Lower |
| Cancer Risk | Redheads | Non-Redheads |
|---|---|---|
| Melanoma | Increased | Decreased |
| Skin Cancer | Increased | Decreased |
| Prostate Cancer | Increased | Decreased |
