Alopecia is a medical condition characterised by hair loss from the scalp or other parts of the body. Food allergies can trigger immune reactions that contribute to the onset and severity of alopecia.
At a recent symposium centred on medical and aesthetic dermatology, research findings were presented on the impact of specific food allergens on hair loss. Through prior studies, atopy, including food allergies, have been identified as the top comorbidity in alopecia areata among adults and children. Sesame emerged as a significant allergen linked to hair loss, with many children testing positive for sesame allergies and experiencing alopecia areata.
When sesame was included as a major allergen in the U.S, some companies started adding sesame to all food items so they could positively label rather than manage cross-contamination risks. This practice has reportedly led to increased allergic reactions and hair loss.
The symposium presentation highlighted some cases in which eliminating specific allergens, like sesame, and environmental factors, such as olive tree pollen, helped alleviate hair loss. These cases help to emphasise the importance of thorough allergy testing when diagnosing and treating alopecia.
