Hair loss in Children

A four-year-old boy presented with progressive hair loss over two months, starting as a small patch at the occipital area of his head, extending to the bilateral temporal and parietal areas. There was no itching, pain, or redness, and no history of hair-pulling or trauma. There was no family history of skin or hair disorders, and developmental milestones were met. The physical examination showed smooth, non-tender skin with patchy hair loss, as shown in the image. Dermatoscopy revealed tiny black dots.
