Mona Lisa Has Alopecia New Medical Theory Suggests
Leonardo da Vinci’s portrait of the Mona Lisa has accumulated a diverse medical diagnosis over five centuries without ever being examined by a physician, according to a report published by t-online.de on October 31, 2026. Housed in the Louvre in Paris, the Renaissance painting now faces a fresh dermatological evaluation suggesting the model may have suffered from alopecia areata.
- Italian dermatologist Luigi Laino published a new clinical theory in the journal Clinics in Dermatology pointing to severe alopecia areata as the cause of the subject’s missing eyebrows, eyelashes, and unusual hairline.
- Previous medical hypotheses advanced by researchers over the last two decades include Xanthelasma linked to elevated blood lipids, benign fatty tumors, and hypothyroidism driven by a characteristic yellowish skin tone.
- Historians and clinicians continue to debate whether the distinct facial features reflect an autoimmune condition or simply contemporary Renaissance beauty standards involving the intentional plucking of facial hair.
Dermatological Evaluation in Clinics in Dermatology
Italian dermatologist Luigi Laino published his analysis in the medical journal Clinics in Dermatology, identifying indicators consistent with a severe form of patchy hair loss known as alopecia areata. In this autoimmune condition, the immune system attacks hair follicles, occasionally resulting in the total loss of scalp and body hair. Laino noted that the absence of eyebrows and eyelashes, combined with a smooth forehead and eye area free of scarring, aligns with the clinical presentation of the disorder. High-resolution examinations of the portrait reveal a single hair situated above one eye, which the author interprets as a potential remnant following widespread hair loss.
Historical Alternative Explanations for Renaissance Aesthetics
Medical assessments of the subject, traditionally identified as Lisa Gherardini, contrast with established historical practices of the 16th century. During the Renaissance, women frequently plucked their eyebrows and hairline to create a higher forehead, a custom considered a standard of beauty at the time. Laino acknowledged this alternative explanation but argued that autoimmune hair loss remains a more convincing clinical fit for the specific combination of facial traits depicted in the oil painting.
Prior Diagnoses of La Gioconda
The latest dermatological assessment adds to a long-standing medical file compiled by researchers studying the artwork over the past two decades. In 2004, Belgian physician Jan Dequeker and his colleagues examined the portrait and identified a yellowish lesion on the eyelid as a potential xanthelasma, which represents a subcutaneous lipid deposit associated with high blood lipid levels. Those same investigators interpreted a perceived swelling on the subject’s hand as a benign fatty tumor. A separate team of specialists proposed a hypothyroid diagnosis in 2018, pointing to a yellowish skin tone alongside thinning hair and absent eyebrows.
Determining whether the individual who sat for Leonardo da Vinci experienced an underlying pathology remains difficult due to the passage of centuries and the inherent limitations of interpreting historical art through modern clinical diagnostics. Researchers continue to debate whether the painted features document actual clinical morbidity or represent artistic choices standard for the period.
