Male pattern baldness is a common condition that affects millions of men worldwide. It is a gradual process that can start as early as the teenage years and progress over time. While some men may embrace their baldness, others may feel self-conscious or embarrassed about their appearance. In this article, we will explore reasons why men experience baldness and what can be done to prevent or treat it.

One of the primary causes of male pattern baldness is genetics. Genetics play a role in up to 80% of cases. Men who have a family history of baldness are more likely to experience it themselves. This is because male pattern baldness is linked to the hormone dihydrotestosterone (DHT), produced from testosterone. For men who are genetically predisposed to baldness, DHT can cause hair follicles to shrink, leading to thinner and shorter hair until eventually, the follicle stops producing hair altogether.

Another factor that can contribute to male pattern baldness is age. As men age, their levels of testosterone decrease, which can lead to hair loss. Additionally, as men age, the hair follicles become smaller, and the hair produced is thinner and more fragile. This can make it more susceptible to damage and breakage, leading to baldness over time. While age and genetics are the most common causes of male pattern baldness, there are other factors that can contribute to this condition.

Genetic Factors

There are several factors that contribute to male pattern baldness, and one of the most significant is genetics. In fact, genetics is the primary cause of baldness in most men.

Androgenetic Alopecia

Androgenetic alopecia, also known as male pattern baldness, is a hereditary condition that affects up to 80% of men at some point in their lives. It is caused by a combination of genetic and hormonal factors and results in a gradual thinning of the hair on the scalp.

The condition is triggered by the hormone dihydrotestosterone (DHT) is produced by the male hormone testosterone. DHT causes hair follicles to shrink and eventually stop producing hair altogether. The extent to which a man is affected by androgenetic alopecia is largely determined by his genetics.

Family History

One of the strongest predictors of male pattern baldness is family history. If a man’s father or other male relatives have experienced baldness, he is more likely to experience it. This is because the genes that lead to baldness are passed down from generation to generation.

Researchers have identified several genes that are associated with male pattern baldness. These genes are involved in the production of DHT, as well as in the regulation of hair growth. While having these genes does not necessarily mean a man will experience baldness, it does increase the likelihood.

Hormonal Changes

Baldness is a common issue for men and can be caused by several factors, including hormonal changes. Hormones regulate the growth and development of hair follicles, and any changes in hormone levels can affect hair growth and cause baldness.

Testosterone Levels

Testosterone is a hormone responsible for the development of male characteristics, including body hair and muscle mass. However, high levels of testosterone can also lead to hair loss. This is because testosterone is converted into dihydrotestosterone (DHT), a hormone that shrinks hair follicles and causes them to produce thinner and shorter hair.

Dihydrotestosterone (DHT) Impact

Dihydrotestosterone (DHT) is a hormone produced from testosterone by the enzyme 5-alpha reductase. DHT is responsible for shrinking hair follicles and causing hair to become thinner and shorter. This hormone is particularly harmful to hair follicles on the top of the head, which are more sensitive to DHT.

In conclusion, hormonal changes affect hair growth and can lead to baldness in men. Understanding the role of hormones in hair growth can help individuals take steps to prevent hair loss and maintain healthy hair.

Age-Related Factors

Hair Growth Cycle Changes

As men age, their hair growth cycle changes, leading to hair loss. The hair growth cycle consists of three phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). As men age, the anagen phase becomes shorter, and the telogen phase becomes longer, leading to less hair growth and more hair loss. Furthermore, the hair that grows during the anagen phase becomes thinner and weaker.

Follicle Miniaturization

Another age-related factor that contributes to baldness is follicle miniaturization. As men age, their hair follicles shrink and produce thinner, shorter hair. Eventually, the hair follicles become so small that they can no longer produce hair, leading to baldness.

To summarize, age-related factors such as changes in the hair growth cycle and follicle miniaturization contribute to baldness in men. While these factors cannot be prevented, treatments are available to slow down the balding process and promote hair growth.

Health Conditions

Thyroid Disorders

Thyroid disorders are a common cause of hair loss in men. The thyroid gland produces hormones that regulate metabolism. When the thyroid gland produces too much or too little hormone, it can lead to hair loss. Hyperthyroidism, where the thyroid gland produces too much hormone, can cause hair to become thin and brittle. On the other hand, hypothyroidism, where the thyroid gland produces too little hormone, can cause hair to fall out in large amounts.

Autoimmune Diseases

Autoimmune diseases, such as alopecia areata, can also cause hair loss in men. Alopecia areata is a condition where the immune system attacks hair follicles, causing hair to fall out in small patches. Sometimes the hair loss can be more extensive, leading to complete baldness. Other autoimmune diseases, such as lupus, can also cause hair loss.

It’s important to note that not all hair loss is caused by health conditions. Male pattern baldness, for example, is a genetic condition not caused by any underlying health problems. However, if you are experiencing hair loss, important to consult a healthcare professional to rule out any underlying health conditions.

Lifestyle Influences

Baldness is a common problem among men and is often caused by genetic and environmental factors. While genetics play a significant role in male pattern baldness, lifestyle choices can cause hair loss.

Nutrition and Diet

A diet lacking in essential nutrients can contribute to hair loss. A deficiency in protein, iron, and zinc lead to weakened hair follicles and hair loss. A diet rich in fruits, vegetables, and lean protein can help support healthy hair growth.

Stress and Anxiety

Stress and anxiety can contribute to hair loss in men. Chronic stress can lead to hormonal imbalances, which can cause hair follicles to enter the resting phase prematurely. This can result in hair thinning and eventually hair loss. Managing stress through exercise, meditation, or therapy can help reduce the risk of hair loss.


Smoking can also contribute to hair loss in men. The toxins in cigarette smoke can damage hair follicles and lead to premature hair loss. Quitting smoking can help reduce the risk of hair loss and improve overall health.

Making healthy lifestyle choices can help reduce the risk of hair loss in men. While genetics play a significant role in male pattern baldness, making small changes to diet and lifestyle can help support healthy hair growth.

Environmental Factors

Pollution Exposure

Pollution exposure is one of the environmental factors that can lead to hair loss in men. Exposure to pollutants like particulate matter, nitrogen dioxide, and sulfur dioxide can damage hair follicles, leading to hair loss. A study conducted in South Korea found that men who lived in areas with high levels of air pollution .Were more likely to experience hair loss than those who lived in areas with lower levels of pollution.

UV Radiation

UV radiation from the sun can also contribute to hair loss in men. Prolonged exposure to UV radiation can damage the hair follicles, leading to hair loss. This is more likely to happen in men already balding. Wearing a hat or using a sunscreen specifically designed for the scalp can help protect against UV radiation and reduce the risk of hair loss.

Overall, environmental factors can play a role in male baldness. Reducing exposure to pollutants and protecting against UV radiation can help reduce the risk of hair loss.


Medications and Treatments


Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells. While it’s effective against cancer cells, it can also damage healthy cells, including hair follicles. This can cause hair loss, which is often temporary and will usually grow back after chemotherapy treatment.

Prescription Drugs

Certain prescription drugs can also cause hair loss in men. One example is finasteride, a medication commonly used to treat enlarged prostate and male pattern baldness. Finasteride blocks the conversion of testosterone into dihydrotestosterone (DHT), a hormone that contributes to hair loss. While it can be effective in promoting hair growth, it can also cause side effects such as decreased sex drive and erectile dysfunction.

Another medication that can cause hair loss is lithium, which is used to treat bipolar disorder. Lithium can disrupt the normal growth cycle of hair follicles, leading to hair loss.


In addition to prescription drugs, some over-the-counter medications and supplements can also contribute to hair loss. For example, high doses of vitamin A can cause hair loss, as can some weight loss supplements.

It is important to talk to a healthcare provider to advice on the best treatment regime. To avoid negative side effects.
