Researchers at Pusan National University in South Korea found that people who regularly drink alcohol are significantly more likely to develop androgenetic alopecia (AGA).
AGA is the most common type of hair loss, affecting millions of men and women worldwide. Previous studies show the condition is driven mainly by genetic and hormonal factors. But new research suggests lifestyle choices can also contribute to hair loss, the Daily Mail reports.
“People who consume alcohol may have a higher likelihood of developing AGA compared to those who don’t drink,” said Professor Yun Hak Kim, the lead researcher.
How do the researchers explain the link?
In their study, the researchers carried out the first meta-analysis of alcohol consumption and hair loss. They found that people who regularly drink alcoholic beverages are 1.4 times more likely to experience androgenetic alopecia than non-drinkers.
The researchers didn’t investigate the exact reasons for the association, but they suggested it could involve acetaldehyde — a byproduct of alcohol metabolism.
“One hypothesis is that acetaldehyde, a byproduct of alcohol metabolism, may affect the immune environment of the scalp and contribute to AGA,” the scientists stated.
Overall, the researchers hope their findings will encourage more studies on the connection between alcohol consumption and hair loss. The research could also help healthcare professionals develop lifestyle recommendations to reduce the risk of baldness.
Although AGA is a concern, especially for men, bald men actually enjoy several social advantages. Studies have found that male baldness is often seen as a form of safe social dominance. Bald men are also perceived as more mature, intelligent, educated, and honest compared with men who have thick hair.
