What Causes Hair Loss

Before we go into detail about testosterone and your hair, it’s important to briefly clear up what exactly male hair loss is, as well as the key factors that cause it to occur. As a man, a variety of different factors can cause you to shed hair. These include stress, issues with your diet, infections, illnesses that cause fever and your use of certain types of medication, such as chemotherapy drugs used in cancer treatment. Even certain hairstyles can cause you to shed hair by pulling on your hair follicles and causing a form of hair loss called traction alopecia. Most of these issues cause temporary hair shedding, such as telogen effluvium. When a dietary problem or stressful work environment takes a toll on your hair, it’s normally possible to get your hair back once you fix the underlying issue. The most common type of hair loss in men, however, is male pattern baldness, or androgenetic alopecia. Unlike most forms of hair loss, which cause temporary shedding, male pattern baldness causes permanent loss of your hair. It usually begins with a receding hairline or bald patch around your crown (the area at the top of your head), before causing a general loss of hair density. Male pattern baldness is common, and it can potentially affect adult men of all ages. It can vary hugely in severity from mild to extensive, with specialists using tools like the Norwood Scale to assess the extent of this type of hair loss. So, what causes male pattern baldness, and how is the hormone testosterone involved? Male pattern baldness occurs due to a combination of genetic factors and the effects of an androgen hormone (the clinical name for a male sex hormone) called dihydrotestosterone (DHT). If you’re genetically prone to pattern hair loss, DHT can attach to receptors located throughout your scalp and cause your hair follicles to gradually become smaller, affecting your hair growth cycle. This process is referred to as follicular miniaturization, and it can eventually lead to hair follicles that are no longer capable of producing new hairs. As you’ve likely noticed, the word “dihydrotestosterone” is similar to “testosterone.” This isn’t a coincidence. Your body produces dihydrotestosterone as a byproduct of DHT via the effects of an enzyme called 5 alpha-reductase. 5 alpha-reductase converts a tiny percentage of your testosterone into DHT in certain types of tissue, particularly in your skin, testes and prostate. During childhood and adolescence, this DHT is important for developing your genitals, prostate and male secondary sex characteristics, such as your voice and body hair. However, as an adult, DHT doesn’t play a major role in your physiology. However, it can cause a variety of health issues, including prostate enlargement and hair loss. Many treatments for male pattern hair loss, such as the oral medication finasteride and hair loss shampoos, work by blocking DHT, either at its source or at the follicular level. We’ve discussed the effects of DHT on your hair in more detail in our full guide to DHT and male hair loss.

Testosterone Injections and Hair Loss

If you’ve been diagnosed with low testosterone levels, your healthcare provider may prescribe a form of therapeutic testosterone to help you increase your levels of testosterone so that they fall within the normal range. Testosterone has important benefits. It’s an anabolic hormone, meaning it helps you to build and maintain skeletal muscle. It also increases red blood cell production, which may lower your risk of developing conditions such as anemia. Research also suggests that testosterone helps to keep your bones healthy, increase your level of energy, help you to maintain a stable mood and promote a consistent sex drive and healthier erections. Taking therapeutic testosterone can help to reduce your risk of dealing with the symptoms of low testosterone, which can include:

Erectile dysfunction (ED)

Although testosterone is often given as an injection, it’s also available as a pill, gel, patch and as an implant that’s placed under your skin. Your healthcare provider will suggest the best form of exogenous testosterone treatment for you based on your needs and preferences. While testosterone itself doesn’t cause hair loss, using testosterone -- whether as an injection or in any other form -- can potentially accelerate the progression of male pattern baldness. This is because, as we mentioned earlier, a small percentage of the testosterone that circulates in your body is converted into dihydrotestosterone, or DHT, by the enzyme 5 alpha-reductase. For healthy men, normal testosterone levels range from 300 to 1,000 nanograms per deciliter of blood (ng/dL). When you increase your testosterone levels by getting a testosterone injection, applying a gel or using a testosterone patch, you provide more testosterone for the 5 alpha-reductase enzyme to use for the conversion of testosterone into DHT. This increase in DHT levels means that the effects of male pattern baldness, such as slow scalp hair growth or noticeable hair thinning, may happen at a faster pace.

Other Potential Side Effects of Testosterone Therapy

If you have low testosterone, using a form of testosterone therapy to increase your testosterone levels can have real benefits for your health, wellbeing and quality of life.

However, testosterone therapy can also potentially cause side effects, including:

Reduced sperm count

Enlarged prostate

Increased cholesterol levels

Difficulty falling asleep or staying asleep

Elevated risk of heart disease

Worsening of heart failure

Increased risk of blood clots

While testosterone therapy may also cause negative effects if you already have cardiovascular disease, it isn’t clear if it increases your risk of stroke, heart attack or diseases such as prostate cancer. If you’re considering using testosterone to treat low-T, it’s important to talk about these potential side effects of hormone therapy with your healthcare provider.

How to Maintain Your Hair and Prevent Male Pattern Baldness

Dealing with hair loss can be a frustrating experience, whether it’s something you slowly notice over time or an issue that accelerates after you start using testosterone. The good news is that male pattern baldness is treatable. Currently, there are two medications that you can use to either slow down, stop or reverse the effects of male pattern baldness and maintain your hair as you get older. The first of these medications is finasteride, an oral prescription medication. Finasteride works by blocking the effects of the 5 alpha-reductase enzyme. This stops your body from converting testosterone into DHT, shielding your hair follicles from DHT-related damage. A typical dose of finasteride can reduce your serum DHT levels by around 70 percent, which is enough to combat hair loss for most men. Clinical studies show that finasteride works well for most men with androgenetic hair loss. For example, a clinical trial from the Journal of the American Academy of Dermatology found that men with pattern hair loss showed improvements after using finasteride over two years. We offer finasteride online, following a consultation with a licensed healthcare provider who will determine if a prescription is appropriate. The second of these medications is minoxidil, a topical treatment that’s available as a solution or foam. Minoxidil doesn’t block DHT, but it does stimulate hair growth by moving your hair follicles into the anagen, or growth, phase of the hair growth cycle. It also increases blood flow to your scalp, which may help your blood vessels supply nutrients to your hair follicles. For example, one study published in the journal Dermatologic Therapy found that more than 94 percent of men with pattern hair loss showed improvements after using finasteride and minoxidil over a period of 12 months. We offer minoxidil solution and minoxidil foam online. You can also buy finasteride and minoxidil together, along with other helpful hair loss treatments, in our Hair Power Pack.
