Medium, short, long Hairstyles for women 2013, and how to choose the most flattering color. Red hair is the rarest natural hair color in humans, a 2007 report in The Courier-Mail, which cited the National Geographic magazine and unnamed “geneticists”, said that red hair is likely to die out in the near future. Other blogs and news sources ran similar stories that attributed the research to the magazine or the “Oxford Hair Foundation”. However, a HowStuffWorks article says that the foundation was funded by hair-dye maker Procter & Gamble, and that other experts had dismissed the research as either lacking in evidence or simply bogus.
The National Geographic article in fact states “while redheads may decline, the potential for red isn’t going away.
Red hair is caused by a relatively rare recessive gene, the expression of which can skip generations. It is not likely to disappear at any time in the foreseeable future.
