Hair loss is a common concern for many people, especially those dealing with androgenetic alopecia (AGA), the most widespread form of hair loss.

AGA affects millions of men and women globally, often impacting self-esteem and social confidence.

While AGA is mainly linked to genetics and hormones, lifestyle factors like smoking, diet, and stress have also been studied.

But what about alcohol? Could drinking affect your hair health?

Alcohol consumption is a widespread habit and is known for its effects on health, such as liver and heart issues.

However, its connection to hair loss, particularly AGA, hasn’t been clear. Some researchers believe that acetaldehyde, a chemical created when alcohol is broken down in the body, might disrupt the scalp’s immune system and play a role in hair loss. But this idea hasn’t been proven yet.

To explore this, Professor Yun Hak Kim from Pusan National University’s School of Medicine led a research team to review and analyze studies on alcohol and AGA.

Their findings were published on November 11, 2024, in the journal Alcohol and Alcoholism.

The study showed that people who drink alcohol might be slightly more likely to experience AGA compared to non-drinkers.

Drinkers were 1.4 times more likely to have AGA, but the difference wasn’t strong enough to be considered statistically significant. Simply put, the evidence doesn’t firmly prove a link between alcohol and hair loss.

Different types of studies showed mixed results. Some smaller studies suggested a weak connection between drinking and AGA, but larger, more reliable studies found no significant link. This means more high-quality research is needed to figure out if alcohol really affects hair loss and how it might happen.

The researchers suggest future studies should have clearer definitions of alcohol use and consistent ways to diagnose AGA. Better research could help answer these questions and lead to more personalized health advice for people concerned about hair loss.

Professor Kim emphasized that their work aims to guide public health recommendations and help individuals make informed lifestyle choices. “Understanding the role of alcohol in hair health could contribute to personalized treatments and prevention strategies for hair loss,” he explained.

While it’s too early to say whether alcohol has a significant effect on AGA, this study is a step toward uncovering the bigger picture of how lifestyle factors impact hair health. For now, a balanced diet, stress management, and consulting a healthcare professional remain key to maintaining healthy hair.
