A double crown refers to a specific pattern of hair growth on the head.
Understanding the Double Crown
Based on the provided information, a "double crown" is characterized by:
- Two whorls in the hair: Unlike the common occurrence of a single whorl.
- Location: Found at the upper back part of the head.
- Proximity: The two whorls are typically about five centimeters apart.
- Direction: Commonly, and probably always, they turn in the same direction.
Essentially, where most people have one circular pattern of hair growth at the back of the head from which hair radiates outwards, someone with a double crown has two such patterns close together.
Characteristics of a Double Crown
Here are the key attributes summarized:
- Number of Whorls: Two
- Typical Location: Upper back head
- Approximate Distance Apart: 5 cm
- Direction of Spin: Usually the same
Visualizing a Double Crown
Imagine looking at the back of someone's head. A standard hair crown looks like a single point where hair seems to spiral out. A double crown presents two distinct, though relatively close, points of spiral hair growth in that same general area.
Significance and Commonality
While the reference doesn't delve into the significance, hair whorls are a natural part of hair growth patterns and are influenced by genetics. Having a double crown is simply a variation of this common pattern and is not associated with any medical condition or particular trait, despite some popular folklore or old beliefs. It's a normal, though less common, anatomical variation.
- Normal Variation: It's just a different way hair grows.
- Genetic Influence: Hair growth patterns, including whorls, are largely genetic.
In summary, a double crown is a distinctive feature of hair growth defined by the presence of two hair whorls in the specific location and proximity described.
