TLDR Alopecia areata caused a boy's hair to regrow straight instead of curly, but the exact reason is unknown.

Alopecia areata (AA) affected a 13-year-old African American boy, causing his hair to change from curly to straight upon regrowth, resembling his early childhood hair. This alteration might have been due to treatment, pathophysiologic changes, or both, though the exact cause remained unknown. Potential factors included stem cell differentiation, cytokine or hormonal influences, or gene expression during hair follicle development. Understanding these triggers could offer insights into AA and influence hair grooming practices.
