Mona Lisa's secret revealed? Doctor points to four symptoms of a rare disease

Recent research suggests that Lisa Gherardini, the woman behind the Mona Lisa, may have suffered from alopecia areata, an autoimmune condition causing hair loss. Dermatologist Dr. Luigi Laino points to four facial features as evidence: the absence of eyebrows and eyelashes, a distinct hairline, and smooth skin. These symptoms, often linked to stress or hormonal issues, appear simultaneously in the painting, strengthening the diagnosis. Gherardini's life was marked by personal tragedies, including the loss of four children, which may have contributed to her condition. The Mona Lisa, painted by Leonardo da Vinci in the early 16th century, remains a major attraction at the Louvre.
