How and why does sweat cause hair loss?
Sweat contains lactic acid, which breaks down the outter layers of hair causing gradual miniaturization of the hair follicles. The damage caused by the acid becomes evident at first when dry, brittle, weak hair is observed.
In addition to damaging the hair, the lactic acid in sweat may cause inflammation, which is strongly believed to have a direct impact on hair growth, due to the restriction of blood supply to the hair (and therfore nutrient supply).
Is your hair loss caused by sweat?
According to Dr Harris-Wells, it’s possible that lactic acid may cause hair loss even in people who don’t suffer from excessive sweating, but if you are someone who experiences above average persperation it’s possible that sweat has had an impact on your hair.
