Consuming carbonated beverages may cause hair loss, according to new study

Could the consumption of carbonated drinks be the reason why you are losing your hair?

People who drink more sugary beverages may also be more likely to experience hair loss, according to an analysis conducted on studies in recent years.

"Diet and nutrition play a crucial role in hair health, especially vitamin D and iron supplements, while limiting alcohol and carbonated beverages may be beneficial," write the researchers from Portugal's Universidade do Porto.

Their findings build on previous findings over the past decade showing that consuming sugary beverages is associated with an increased risk of hair loss in men and that inflammation caused by consuming these foods helps with this problem.

Just 11 cans of sugary drinks per week, or more than 3,500 milliliters, left young people at a higher risk for male pattern hair loss, according to a 2023 study cited in the new analysis. At the time, the Tsinghua University authors said it was difficult to determine a cause and effect between the two factors because it relied on data reported by its 1,028 participants.

Sugary beverage consumption has also been linked to obesity, tooth decay, and other problems that have been linked to hair loss.

But, the Portuguese authors noted that the 2023 discovery was supported by a 2016 study that found that consuming processed foods containing simple sugars was an "indirect factor associated with hair loss."

This is because foods stimulate the production of excess sebum, the oily substance we produce that moisturizes the skin and hair. This leads to the growth of bacteria on the scalp that can result in irritation and inflammation, which contribute to hair loss.

"The findings suggested that targeted dietary interventions may be important in preventing and managing hair problems such as alopecia and hair loss. However, further research is needed to deepen our understanding of these links and develop evidence-based recommendations for promoting hair health through nutrition," the authors write.
