Crown pattern

Hereditary male-pattern hair loss can create a bald spot at the top of the head, but crown visibility alone does not identify a cause. [source]

Photography mistakes

  • Direct flash centered on the whorl
  • Wet hair in only one comparison
  • Changing the camera height
  • Cropping so tightly that the surrounding area is lost

When to get it checked

Rapid, patchy, inflamed, painful, scaly or scarred change needs professional assessment. These features can fall outside a typical gradual pattern. [source]
