A popular social media trend has sparked concern among medical professionals as people are resorting to using fruit to achieve sun-kissed blonde hair.
However, people are being warned that doing so could lead to a painful medical 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 attempting to naturally lighten their hair using the citrus fruit's juice. In a stern warning, Dr Rajan stated: "The citric acid from the lemon interacts with UV rays from the sun and makes the hair more photosensitive.
This accelerates melanin breakdown in the hair causing a lightening of the hair colour. £But the acidity of lemon juice can also strip the hair of its natural oils leading to dryness and increased hair fragility.
