Does Testosterone Really Cause Hair Loss?

Does Testosterone Cause Hair Loss

If you’re worried about hair loss, you may have heard that testosterone is the culprit. Is this really true? In this article, we’ll delve into the relationship between testosterone and hair loss to determine if there’s any truth to this common belief. So, let’s explore the science behind it!

Understanding Testosterone and Its Functions

Before we jump into the connection between testosterone and hair loss, let’s understand what testosterone is and its role in the body. Testosterone is a hormone primarily produced in the testicles in men and ovaries in women. It plays a vital role in the development of male physical characteristics, such as muscle mass, bone density, and regulating sex drive and sperm production.

Interestingly, testosterone is also linked to hair growth and loss. The reason behind this connection lies in the conversion of testosterone into dihydrotestosterone (DHT), courtesy of an enzyme called 5-alpha-reductase. DHT is a hormone known for causing hair follicles to shrink, which leads to hair loss.

The Complexity of Testosterone and Hair Loss

So, does testosterone directly cause hair loss? The answer is not that simple. While testosterone itself isn’t the main culprit, the conversion of testosterone into DHT does play a role. However, it’s essential to consider other factors such as genetics, age, and lifestyle choices that can contribute to hair loss.

Let’s take a closer look at the relationship between testosterone and hair loss, along with the factors that can influence this connection.

Types of Hair Loss

There are several types of hair loss, each with its own unique causes and characteristics. The most prevalent type is androgenetic alopecia, also known as male or female pattern baldness. Other types include telogen effluvium, alopecia areata, and traction alopecia.

Testosterone and Male Pattern Baldness

Male pattern baldness is primarily caused by genetics, although testosterone and DHT also play a role. This type of hair loss usually starts with a receding hairline and thinning at the crown, eventually leading to complete baldness.

The Role of DHT in Hair Loss

As mentioned earlier, DHT is formed when testosterone is converted by the enzyme 5-alpha-reductase. DHT can cause hair follicles to shrink, resulting in hair thinning and loss. That’s why DHT blockers are commonly used to address male pattern baldness. These blockers prevent the conversion of testosterone into DHT.

While testosterone itself doesn’t directly cause hair loss, it can contribute to the process. Understanding the role of DHT and its impact on hair follicles is crucial in treating and preventing hair loss.

Factors Affecting Testosterone and Hair Loss

Various factors can influence testosterone levels and hair loss. Age is one of the significant factors, as testosterone levels naturally decline as men get older. By the age of 70, the average man’s testosterone levels are about 50% lower than they were in his 20s.

Medical conditions like obesity, diabetes, and thyroid problems can also impact testosterone levels. Additionally, certain medications and treatments, such as chemotherapy and radiation therapy, can lower testosterone levels.

Lifestyle choices also play a significant role. High-stress levels can increase cortisol production, which, in turn, lowers testosterone levels. Diet is another factor to consider. A diet high in processed foods and sugar can cause inflammation, negatively affecting testosterone levels. On the flip side, a diet rich in healthy fats can boost testosterone levels.

Exercise, especially resistance training, has been shown to increase testosterone levels. This can be beneficial for individuals experiencing hair loss due to low testosterone levels.

In summary, lifestyle factors like diet, stress management, and regular exercise can impact testosterone levels and potentially reduce the risk of hair loss.

Treatment Options for Testosterone-Related Hair Loss

If you’re facing hair loss due to testosterone, several treatment options are available. Here are some of the most common ones:


Two FDA-approved medications, finasteride and minoxidil, can help treat hair loss caused by testosterone. Finasteride blocks the conversion of testosterone into DHT, while minoxidil improves blood flow to the scalp and stimulates hair growth. These medications can be effective, but they come with potential side effects.

Hair Transplant Surgery

Hair transplant surgery involves relocating hair follicles from one area of the scalp to the balding area. This invasive procedure can be effective, but it can be costly and may require multiple sessions.

Low-Level Laser Therapy

Low-level laser therapy (LLLT) stimulates hair growth using red or near-infrared light. This treatment can be conveniently performed at home using a specialized laser cap or helmet. Although generally safe and painless, it can take several months to see results and may not work for everyone.

Scalp Micropigmentation

Scalp micropigmentation involves tattooing tiny dots on the scalp to replicate the appearance of hair follicles. It’s a non-invasive procedure that can be completed in a single session and is a good option for those who aren’t suitable candidates for hair transplant surgery or want to avoid medication. However, it does require regular touch-ups to maintain its appearance.

It’s essential to consult with a healthcare professional or hair loss specialist to determine the best treatment option based on your specific needs.


In conclusion, the relationship between testosterone and hair loss is complex and multifactorial. While testosterone itself isn’t solely responsible, the conversion of testosterone into DHT can contribute to hair loss. Other factors such as genetics, age, and lifestyle choices also play a role.
