As the festive season approaches, scientists from Pusan Nation University in South Korea have made a discovery that will be unwelcome for some: there may be a possible link between alcohol consumption and male pattern baldness (androgenetic alopecia). Neuroscience News reports that drinkers were 1.4 times more likely to have the condition.
There is some comfort for those who enjoy a tipple: the evidence is inconclusive and further research is needed. Professor Yun Hak Kim, who led the research, explains: “The study found that although individuals who consume alcohol may have a slightly higher likelihood of experiencing AGA compared to non-drinkers, this association is not statistically significant.”
However, given what we already know about the dangers of alcohol consumption, it’s certainly an issue worth exploring further as the holiday season gears up, bringing with it more opportunities to drink than usual. Here’s a closer look at the issue.
What is male pattern baldness?
Male pattern baldness (MPB) is the most common form of hair loss in men, affecting about half of all middle-aged males. The primary cause is genetic and hormonal factors: some men are more sensitive to a hormone called dihydrotestosterone (DHT), which causes the hair follicles in the scalp to shrink and eventually die.
There is no cure for MPB, but there are a few clinically proven treatments. One of the most popular and cheap to buy is finasteride. It works by inhibiting the production of DHT to slow down hair loss, and if the treatment is started early enough, it may be able to reverse the effects altogether for as long as the medication is taken.
Why might alcohol consumption increase the rate of hair loss?
The study does not offer any conclusive reasons for the potential link between alcohol consumption and hair loss. However, one theory put forward by the authors is that acetaldehyde, a byproduct of alcohol metabolism, may interfere with the functioning of the hair follicles.
Other possible reasons might include hormonal imbalances, nutritional deficiencies, and oxidative stress, although these issues are likely to be caused by long-term excessive alcohol consumption rather than occasional or moderate drinking.
The psychological impact of MBP
MPB is not usually associated with serious health problems, but the emotional and psychological impacts should not be underestimated. Hair loss can affect confidence and self-esteem, particularly in a society that places a heavy emphasis on a youthful appearance.
The implications of the study
The researchers believe that their study could lead to more tailored and effective treatment plans for hair loss in the future.
Prof. Kim comments: “Our research could inform public health guidance, patient counselling, and targeted awareness campaigns, helping individuals make informed lifestyle choices regarding hair health.”
“Over time, this could contribute to more comprehensive, personalized health strategies, where factors like diet, genetics, and lifestyle are better understood and integrated into prevention and treatment plans for hair loss.”
Tips for moderate drinking during the festive season
Whether or not alcohol might exacerbate hair loss, there is a substantial body of evidence to prove the link between alcohol consumption and a range of serious health issues, including cancer, liver disease, and cardiovascular disorders. It also disrupts sleep, and can cause temporary erectile dysfunction.
At this time of year, it may not be realistic to avoid alcohol consumption entirely, but it’s important to enjoy it responsibly. The UK’s recommended guidelines are to consume no more than 14 units per week, and to avoid consuming more than six to eight units in a single session. Here are some tips to moderate your alcohol intake over the festive season.
Opt for low-alcohol options: at one time, there was a very limited range of low-alcohol drinks available, but now the industry has caught up with increased demand and there are some high-quality options with no compromise on taste.
Alternate alcoholic drinks with water or soft drinks: On a big night out, have a glass of water or a soft drink for every alcoholic drink. This will reduce your intoxication levels, and you will also spend less, stay better hydrated and hopefully avoid a hangover in the morning.
Manage your triggers: If you know that certain triggers make you reach for a drink, put strategies in place to manage them, such as distractions, or deciding before you go to the pub that you are going to resist social pressure and stick to non-alcoholic options.
