The doctor warns about the health condition caused by rubbing lemons on the hair

A popular social media trend has raised concerns among medical professionals as people resort to using the fruit to achieve sun-kissed blonde hair. However, people are warned that this could lead to a painful condition.

Dr Karan Rajan, an NHS surgeon, has issued a warning against the practice of rubbing lemons on your hair during summer. The trend involves people trying to lighten their hair naturally using citrus juice.

In a stark warning, Dr Rajan said: ‘The citric acid in lemon interacts with the sun’s UV rays and makes hair more photosensitive. This accelerates the breakdown of melanin in the hair, causing the hair color to lighten.

£But the acidity of lemon juice can also strip hair of its natural oils, leading to dryness and increased brittleness. The real problem comes when it reaches the scalp and skin.

“Citrus fruits contain chemicals called psoralens, and when exposed to sunlight, UV radiation activates the psoralens, leading to a phototoxic reaction that causes inflammation and damage to skin cells. This is known as phytophotodermatitis”.

Phytophotodermatitis is not considered a serious condition. Although, its effects can persist for weeks or even months, according to Healthline.

Over time, the affected areas clear up on their own, but they can be helped with a few remedies. Recurring cases of phytophotodermatitis are not common because once you get the condition, you are more likely to be careful outdoors and avoid certain plants and fruits to prevent future exposure.

Dr Rajan advised: “If your skin comes into contact with citrus juice and you are in the sun for extended periods of time, wash the affected areas with soap and water to remove the psoralens. If you already have symptoms, then a cold. compresses and consider over-the-counter antihistamines and hydrocortisone creams to reduce inflammation.”
