The Mona Lisa may lack eyebrows and eyelashes due to a medical condition, according to a study by Dr. Luigi Laino. He suggests that Lisa Gherardini might have had alopecia areata universalis, based on visible features in the painting. Other theories include the possibility of Leonardo da Vinci initially painting these details, which may have faded over time, or beauty standards of the Renaissance that favored the removal of facial hair. However, no definitive diagnosis can be made, as the analysis relies on artistic representation rather than medical examination.
