Last year, doctors concluded that eight-year-old Sama Tubail's hair loss was a result of "nervous shock," specifically after her neighbor's house in Rafah was hit by an Israeli air strike in August.

Sama's mental anguish intensified after she was bullied by other children for her hair loss, leading her to retreat indoors. Outside, she wears a pink bandana to cover her scalp.

UNICEF, the United Nations' children's agency, estimated in a report last June that nearly all of Gaza's 1.2 million children need psychological support, especially those exposed to repeated traumatic events.
