Hair whorl

Hair whorl is a patch of hair growing in a circular direction around a visible center point. Hair whorls, also known as crown, occur in most individuals at the top of the scalp. The direction and location of hair whorls can be used to predict the direction of the underlying brain fibers.

Overview[edit | edit source]

Hair whorls have been studied for their correlation with brain development and neurological disorders. They are also used in the field of forensic science to help identify individuals. The direction of a hair whorl can be either clockwise or counterclockwise. The majority of people, about 90%, have clockwise hair whorls.

Genetics[edit | edit source]

The genetics of hair whorls is not fully understood. It is believed that the direction of a hair whorl is determined by the genes, but the specific genes involved are not known. Some studies suggest that hair whorl direction is influenced by the same genes that determine handedness and brain lateralization.

Hair Whorl and Neurological Disorders[edit | edit source]

Some research suggests that the direction of hair whorls is related to certain neurological disorders. For example, a higher percentage of people with schizophrenia have counterclockwise hair whorls compared to the general population. However, more research is needed to confirm these findings and understand the underlying mechanisms.

Hair Whorl in Animals[edit | edit source]

Hair whorls are also found in animals, particularly in horses. In horses, the location and direction of hair whorls can provide information about the horse's temperament and behavior.
