Alcohol and Hair Loss

Alcohol and Hair Loss: What Patients Should Know

Alcohol is one of those habits many people see as harmless in moderation. Yet I meet patients every week who quietly ask whether their drinking could be contributing to their thinning hair. The answer is not straightforward, but the evidence suggests that frequent or heavy alcohol use can worsen hair loss through hormonal disruption, nutritional deficiencies and chronic inflammation in the body.

Regular alcohol intake can interfere with the absorption of vital nutrients required for hair growth, including zinc, iron, folate and protein. These are fundamental building blocks for healthy follicle function. A study found that individuals with alcohol dependence were significantly more likely to experience diffuse hair shedding, and more likely to show deficiencies in zinc and folic acid. When the body prioritises basic survival over non essential functions such as hair production, follicles shift into a resting phase, leading to noticeable thinning over time.

There is also the question of hormones. Alcohol can increase circulating levels of oestrogen while lowering testosterone, and can indirectly influence dihydrotestosterone, the hormone closely linked to male pattern baldness. In men and women with a genetic tendency towards androgenetic alopecia, this hormonal imbalance can accelerate the rate of hair miniaturisation. The effect is not immediate, but gradual, often mixed with other factors like stress, poor sleep and diet.

Patients are often surprised at how stress interacts with alcohol in the context of hair loss. Many use alcohol in the evenings to unwind, but it disrupts sleep quality and increases cortisol levels. Elevated cortisol has been shown to damage the hair growth cycle and can push follicles into the shedding phase known as telogen effluvium. You might notice more hair on the pillow, in the shower or your brush weeks after a stressful period combined with heavier drinking.

Those considering treatment, including a hair transplant, frequently ask whether cutting down on alcohol will make a difference. In many cases it does. Reducing intake allows the liver to recover, hormones to stabilise and nutritional deficiencies to improve. For patients exploring surgical options such as follicular unit extraction, we advise a period of reducing alcohol intake beforehand to ensure the scalp and body are in the best possible condition for healing and graft survival. At My Hair UK, the typical cost of a hair transplant ranges from around £2,899 for 1000 grafts to roughly £4,899 for 3,500 grafts, depending on what is required to achieve natural coverage. Alcohol does not prevent successful outcomes but avoiding it particularly during the healing process is important, but good overall health often leads to better growth and less post operative shedding.

Before committing to surgery, I encourage patients to have a health check with their local GP. This should include blood tests to assess liver function, full blood count, thyroid profile, ferritin and vitamin D. Discuss alcohol use openly. GPs are used to these conversations and can offer support or referral services if cutting back is difficult. A baseline health assessment provides clarity and makes the hair consultation far more productive.

In cases where alcohol intake has been high for many years, hair thinning may be part of a broader systemic issue. Chronic liver disease, anaemia and malnutrition can all display symptoms in the hair, skin and nails. Some patients only discover raised liver enzymes or low iron during routine blood tests before surgery. This is exactly why early investigation matters.

Alcohol alone rarely causes permanent baldness. Genetics remain the dominant influence in pattern hair loss, but alcohol can act as an accelerator in those already predisposed. The decision to address it is not about blame or lifestyle criticism. It is about stacking the odds in your favour, whether you choose medication, nutritional therapy or transplant surgery.

For anyone concerned about their hair and unsure whether alcohol might be a contributing factor, it is worth asking yourself whether your intake affects sleep, mood or diet. Does it replace meals, reduce your appetite or leave you dehydrated in the morning. These small details make a larger difference than people realise.

Hair health responds to consistency rather than perfection. Reducing alcohol, eating balanced meals rich in protein and iron, correcting deficiencies, and addressing stress all contribute to a healthier scalp environment. When these foundations are in place, surgical treatments achieve higher success rates and patients feel more confident throughout the recovery process.
