A small number of people — about five percent of the population — have two hair whorls, or a “double crown.” Many researchers agree that cowlicks develop primarily due to your genetic ...

Your hair that grows from this point in your scalp is arranged in a circular formation that’s called a “whorl.” When you have two “whorls” at the crown of your head, it’s called a ...

Obviously, human heads are not spherical, but they are round on top, and so we all have hair whorls. Most humans—98.5 percent—will have only one, while a lucky 1.5 percent will have two ...

The study identifies four associated genetic variants (at 7p21.3, 5q33.2, 7q33, and 14q32.13). These genetic variants are likely to influence hair whorl direction by regulating the cell polarity ...

[Related: What’s at the root of gray hairs?] Now, a gene mapping study on human scalp hair whorls—a patch of hair growing in a circular pattern around a single point that is determined by the ...
