Sweat and Hair Loss: Is Sweat Bad for Your Hair?

Sweaty scalp hair loss
Have you ever noticed bald and balding people often seem to sweat more than average around their temples? Well there seems to be a connection. In fact Dr Harris-Wells of Miyohara International Trichology Clinic has claimed that sweat has a direct impact on hair growth.

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.

Hold Your Horses

Before you go off and do everything you can to reduce your sweat levels let’s consider the other side of the argument. Although the hypothesis that sweat (or the lactic acid it contains) causes hair loss due to it’s effect on keratin, there are no empircal studies that prove this to be the case.
Probably the very fact that a person is experiencing excessive sweating is the most important sign that they may have an underlying problem, which may be the true cause of the hair loss. Whether the underlying cause of the sweating is anxiety, stress, liver problems or poor diet; all of these things are possible causes of hair loss.
