Natural redheads are becoming rarer and, by one estimate, may have disappeared completely by 2100.

If predictions by the Oxford Hair Foundation come to pass, the number of natural redheads everywhere will continue to dwindle until there are none left by the year 2100.

The reason, according to scientists at the independent institute in England, which studies all sorts of hair problems, is that just 4 percent of the world’s population carries the red-hair gene. The gene is recessive and therefore diluted when carriers produce children with people who have the dominant brown-hair gene.

Dr. John Gray’s often publicized explanation of his foundation’s findings: “The way things are going, red hair will either be extremely rare or extinct by the end of the century.”
