Hair swirls, also known as hair whorls or crowns, are the patterns created by the direction of hair growth on the scalp. These patterns are largely determined by the direction your hair follicles grow, which is influenced by genetics.
Genetics and Hair Swirls
Multiple genes influence the direction and pattern of hair growth, resulting in the unique swirls seen on individual heads. While the exact genes haven't all been identified, research indicates a hereditary component, meaning hair whorl patterns can be passed down through families.

Variations in Hair Swirls
The direction of the swirl (clockwise or counterclockwise) varies between individuals, and multiple swirls are possible. Many people have a single prominent swirl, while others might have two or even more. The location and number of swirls are also influenced by genetics.

Atypical Hair Swirls and Developmental Disorders
While most hair whorl patterns are considered normal variations, atypical patterns—such as abnormally placed or multiple whorls—have, in some cases, been associated with early brain developmental disorders and certain dysmorphic syndromes.

Unusual hair patterns alone are not diagnostic of any disorder.
Cultural Interpretations
Interestingly, different cultures have varying interpretations of hair whorl patterns, sometimes associating specific directions or numbers of swirls with personality traits or cultural significance. For instance, some Filipino cultures associate clockwise swirls with positive attributes. Source: What is this called? It's like where all of your hair gets direction from ... | Reddit
Conclusion
In short, hair swirls are primarily determined by the direction of hair follicle growth, which is genetically influenced. While most variations are normal, atypical patterns might be associated with some developmental disorders in certain cases.
