Hair loss affects millions of people all over the world, but few understand where it comes from. It’s a complex issue with many potential causes and treatments, so it can be overwhelming to try and figure out why you may be experiencing hair loss. In this article, we’ll explore what could be causing your hair loss and how to address it head on.

Hair loss doesn’t discriminate – both men and women experience thinning hair or baldness at some point in their lives. While genetics play an important role, there are other factors that contribute to this condition as well. Environmental influences such as diet, stress levels, hormones, certain medications and lifestyle choices can all have an impact on the health of your scalp and follicles. So if you’re wondering “where does hair loss come from?”, read on for more information!


Hair loss affects around 40% of men and 21% of women in North America. It can be a devastating condition, disrupting not only physical appearance but also confidence and self-image. Understanding the cause of hair loss is necessary to effectively manage it—but what causes it? Genetics play an important role.

Genetic predisposition determines the majority of cases of male pattern baldness (MPB), which accounts for 95% of all hair loss in men. This type of MPB is due to a combination of genetic factors interacting with hormones called androgens. Androgens are responsible for triggering genes that control how sensitive individual follicles are to DHT (dihydrotestosterone). If these follicles become overly sensitive, they enter into a resting state which leads to gradual thinning until eventually the hair falls out completely.

In addition, certain inherited conditions such as alopecia areata or trichotillomania lead to various types and patterns of hair loss depending on their severity and duration. Alopecia generally appears as patches while trichotillomania includes pulling out one’s own hair resulting in noticeable bald spots over time. While genetics certainly have bearing on our chances of experiencing hair loss, there are other environmental factors at play too…

Environmental Factors

Stress can definitely be a factor in hair loss; it can cause the hair to thin out or even fall out in more extreme cases. Sun exposure can also lead to hair thinning, but this is more common in people with naturally lighter hair. Pollution is another environmental factor that can contribute to hair loss, as the toxins in the air can damage the hair follicles. All of these environmental factors can be hard to avoid, but taking steps to reduce stress and limit sun and pollution exposure can help. It’s also worth speaking to a doctor if you’re concerned about hair loss, as they can advise on the best course of action.


The stressful reality of hair loss is one that no one wants to face. It’s an extremely common issue, and can be caused by a variety of environmental factors such as stress. Stress has been linked to both temporary and permanent forms of hair loss, making it essential for people to understand how emotional stress affects the body in order to protect their hairline.

When we experience extreme levels of stress, our bodies respond with hormones like cortisol which cause inflammation in the scalp area leading to physical changes that manifest as hair loss. This type of stress-related baldness is usually reversible once the source of stress has been removed, but unfortunately this isn’t always the case. In some instances where high levels of sustained stress are present over a long period of time, chronic alopecia (permanent hair loss) may occur due to permanent damage done to the follicles.

It’s important for people who are experiencing any form or amount of hair loss to keep track of their lifestyle and consider if there are any sources of psychological distress that could be contributing towards it. Identifying potential causes early on is key when trying to manage or prevent further damage from happening.

Sun Exposure

When it comes to environmental factors that can cause hair loss, the sun is an often overlooked culprit. Sun exposure can be particularly damaging for people with lighter hair colors due to its ability to bleach out pigment from the follicles. Over time, this will lead to thinning and breakage in areas that are exposed to direct sunlight, such as the forehead or part of your scalp. Additionally, UV radiation has been linked to damage on a cellular level which could potentially inhibit new hair growth over time.

The best way to protect yourself against these effects is by limiting your amount of sun exposure and using protective measures such as wearing hats or applying sunscreen when you do go outside. You should also try avoiding long periods of intense heat and humidity if possible since both have been known to increase the rate of hair loss in some individuals. It’s important to remember that even though we may not realize it at first, our environment plays a big role on our overall health – including the condition of our hair!

Taking steps like these now can help you maintain healthy locks for years to come so don’t hesitate to make sure you’re doing what you need in order to keep your mane looking great.


While the sun can be a major contributor to hair loss, there are other environmental factors that we need to consider. Pollution is one of those important factors. From car exhausts to industrial smoke, they all contain chemicals and particulates which have been shown to cause damage to our hair follicles. In some cases, this can lead to thinning and breakage in areas exposed to these pollutants. Not only that, but long-term exposure has also been linked to hormonal imbalances which could inhibit new strands from forming altogether.

The best way for us to protect ourselves against the effects of pollution is by limiting our exposure as much as possible. We should try not living too close or spending too much time near busy roads or factories where air quality is poor. If you want an extra layer of protection, wearing protective masks when outdoors may help filter out some of these harmful substances before they reach your lungs or scalp. Taking small steps like these now can go a long way in preventing any potential health issues down the road.

It’s easy for us forget about how damaging certain environmental conditions can be on our bodies – especially our hair! But with just a little bit of effort and mindfulness, we’ll be able take proactive measures that will keep both our locks and overall health looking great for years come.

Treatments And Prevention

Hair loss has many potential causes, ranging from genetics to lifestyle factors. Treatments and prevention vary depending on the cause of hair loss and can include medications, topical treatments, or even surgery.

Medications are a common choice in treating hair loss due to genetic predisposition or age-related thinning of the follicles. These commonly consist of prescription drugs that help slow down the progression of hair loss or encourage new growth. Topical treatments such as shampoos and conditioners may also be prescribed, which work by nourishing the scalp and stimulating healthy growth. Surgery is usually reserved for more extreme cases where other methods have not been successful. It involves transplanting healthy donor hair into areas affected by baldness.

No matter what type of treatment you choose, it’s important to remember that most forms of hair loss take time to reverse, so patience is key when seeking out solutions for your individual situation. There are also some lifestyle changes you can make to reduce your risk of developing hair loss in the future – avoiding certain triggers like stress and smoking, maintaining a balanced diet including plenty of protein and vitamins, exercising regularly, using gentle styling techniques rather than harsh chemicals or heat tools, limiting sun exposure etc. Taking these steps can go a long way towards preserving your locks!


In conclusion, hair loss can be caused by both genetic and environmental factors. It is important to understand the possible causes of this condition in order to find the most effective treatment for it. According to recent studies, more than 50% of men suffer from some degree of alopecia or balding by their fifties; however, proper care may help prevent further hair loss. I hope that with a better understanding of where hair loss comes from, we can work together towards finding solutions that will benefit everyone affected by this condition.
