Genetics or Lifestyle: Who’s Really to Blame for Your Premature Hair Loss?

▴ Genetics or Lifestyle
By making conscious decisions about your health and well-being, you can tip the scales in your favour and give your hair the best chance to thrive.

For many men, especially younger ones, premature hair loss can feel like a losing battle. It can begin as early as the late teens or twenties, and the first instinct for many is to blame it on genetics. Hair loss, particularly male pattern baldness (MPB), has been around for centuries, but in today’s world, the condition seems to be more prevalent than ever. However, the question remains: is hair loss purely a genetic issue, or could your diet and lifestyle choices be accelerating the process?

Let’s dive into both sides of the argument, exploring the scientific evidence behind genetic predisposition and the role that nutrition and lifestyle play in hair health. As you read on, you’ll discover that while genes may set the foundation for baldness, there are several actions you can take to slow down or even prevent premature hair loss.

Male pattern baldness, or androgenetic alopecia, affects a significant portion of the male population. By the age of 50, around 50% of men experience some form of hair loss, and for many, it begins much earlier. The main cause of MPB lies in the hormone dihydrotestosterone (DHT), a byproduct of testosterone. DHT binds to hair follicles, causing them to shrink, weaken, and eventually stop producing hair altogether.

This genetic sensitivity to DHT is often inherited, and studies show that the likelihood of experiencing MPB can be passed down from both sides of the family. Contrary to popular belief, it’s not just the father’s side that plays a role in male hair loss. A 2017 study published in PLOS Genetics identified over 250 genetic regions associated with hair loss, some of which come from the maternal side.

So, if your father or grandfather experienced hair thinning or balding, there is a good chance you may inherit this trait. However, it’s not an inevitable fate. The timing and severity of hair loss can be influenced by several factors, including how well you take care of your body.

Diet: A Hidden Culprit?
While genetics play a significant role, it’s not the whole story. Emerging research highlights the importance of diet in maintaining healthy hair. Hair follicles, like other parts of the body, need essential nutrients to function optimally. A deficiency in these nutrients can worsen hair loss.

Here are some key nutrients that play a role in hair health:

- Biotin (Vitamin B7): This water-soluble vitamin is crucial for the production of keratin, the protein that makes up hair strands. A deficiency in biotin can lead to brittle hair and even hair loss. Although biotin deficiency is rare, it can occur in people with poor diets or specific health conditions.

- Zinc: Zinc is essential for cell growth and tissue repair, which includes hair growth. A lack of zinc can weaken hair follicles, leading to thinning hair and even bald patches. Ensuring adequate zinc intake is vital for hair follicle health.


- Iron: Iron deficiency is one of the most common nutritional causes of hair loss. This is because iron helps red blood cells carry oxygen to hair follicles. Without enough oxygen, the follicles can weaken, leading to hair shedding. A study in Dermatology Practical & Conceptual found that low iron levels were linked to hair loss in men.

- Protein: Since hair is primarily made up of a protein called keratin, it’s essential to consume enough protein to support healthy hair growth. If your body doesn’t receive enough protein, it may prioritize other vital functions over hair production.


So, what does this mean for men experiencing premature hair loss? While you can’t alter your genetic predisposition to baldness, you can ensure that you’re not accelerating the process by neglecting your nutritional needs. A balanced diet that includes these essential nutrients may help slow down the rate of hair loss and even promote regrowth in some cases.

The relationship between testosterone and hair loss is complex and well-studied. In the 1940s, Dr. James Hamilton discovered a link between male pattern baldness and testosterone during his research at a mental health hospital. He found that men with lower levels of testosterone retained their hair, while those with higher levels were more likely to go bald.

The hormone dihydrotestosterone (DHT), derived from testosterone, is the primary culprit in androgenetic alopecia. DHT binds to receptors in the scalp, causing hair follicles to miniaturize over time. This process gradually reduces the size and quality of hair until the follicles eventually stop producing hair altogether.

While this genetic sensitivity to DHT largely determines who will experience hair loss, lifestyle factors can also influence how quickly this process occurs.

Can Lifestyle Choices Affect Hair Loss?
Beyond diet, other lifestyle factors can play a role in hair health. Stress, for example, has long been linked to hair loss. High levels of stress can cause a condition known as telogen effluvium, where hair follicles enter a resting phase and eventually fall out. While telogen effluvium is usually temporary, it can worsen the effects of male pattern baldness for those already predisposed to it.

Additionally, poor scalp health can contribute to hair loss. A scalp that is clogged with oil, dead skin, or product build-up may not provide a healthy environment for hair growth. Keeping the scalp clean and well-nourished is important for maintaining healthy hair follicles.

Moreover, exercise plays a role in overall health, including hair health. Regular physical activity improves blood circulation, which can help ensure that hair follicles receive the oxygen and nutrients they need to grow. Exercise can also help regulate hormone levels, including DHT, which may slow down the hair loss process.

While hair loss is a modern concern for many men, it’s certainly not a new one. Historical accounts show that people have been trying to combat baldness for centuries, often with questionable remedies.

In ancient Egypt, for example, people mixed concoctions of animal fats and herbal remedies in an attempt to restore hair. The Greek physician Hippocrates famously tried to cure his own baldness with a mixture of opium and pigeon droppings, though without success. Even Julius Caesar, the Roman emperor, struggled with thinning hair and is credited with inventing the first “comb-over.”

Although these ancient remedies were largely ineffective, they highlight a timeless human concern about hair loss. In contrast, modern science offers more effective treatments, such as finasteride and minoxidil, both of which have been shown to slow or halt hair loss in men.

Finasteride works by blocking the conversion of testosterone into DHT, thus reducing the amount of DHT in the scalp and slowing hair follicle miniaturization. Minoxidil, on the other hand, increases blood flow to the scalp, promoting hair growth and slowing the progression of baldness.

Can Hair Loss Be Prevented?

While there is no guaranteed way to prevent hair loss entirely, there are several steps men can take to slow down the process:

1. Dietary Changes: Ensuring that your diet is rich in hair-healthy nutrients like biotin, zinc, iron, and protein is a key step in maintaining hair health.

2. Manage Stress: Chronic stress can exacerbate hair loss. Incorporating stress-relieving activities such as meditation, exercise, or hobbies into your routine can help mitigate its effects.


3. Scalp Care: Regular scalp massages and keeping your scalp clean and free from product build-up can help create an environment conducive to hair growth.

4. Consider Medical Treatments: If you’re concerned about premature hair loss, consult with a doctor or dermatologist about options like finasteride and minoxidil. These treatments can slow hair loss and, in some cases, even promote regrowth.

While genetics certainly play a significant role in premature hair loss, it’s important to recognize that other factors such as diet, stress, and lifestyle choices also influence the health of your hair. By taking a proactive approach that includes a balanced diet, stress management, and proper scalp care, men can slow down the progression of hair loss and maintain a healthy head of hair for longer.

Ultimately, the battle against baldness may be rooted in your DNA, but the outcome isn’t set in stone. By making conscious decisions about your health and well-being, you can tip the scales in your favour and give your hair the best chance to thrive.
