Male Hair Loss Blood Test: Causes and How to Manage Hair Health

Male hair loss is a common issue, affecting millions of men around the world. While it’s often considered a normal part of ageing, the causes of hair loss are much more varied and complex. Understanding these underlying causes is crucial to addressing the issue effectively and finding the right solutions.


Whether it’s a sudden increase in hair shedding or gradual thinning over time, knowing what’s behind your hair loss can help you take proactive steps to manage it. The Male Hair Loss Blood Test by One Day Tests provides insights into the key factors that might be contributing to your hair loss, including hormone levels, stress markers, and overall health.

What Are the Main Causes of Male Hair Loss?

Male hair loss is often a multifactorial condition, meaning that several causes may be at play at once. Understanding these causes is key to addressing hair loss effectively. Here are some of the most common factors contributing to male hair loss:


1. Stress


Chronic stress can have a significant impact on hair health. When the body is under constant stress, it produces elevated levels of the hormone cortisol. High cortisol levels can negatively affect hair growth by pushing hair follicles into a resting phase known as telogen effluvium, where hair sheds prematurely. Stress-related hair loss is often temporary, but if stress continues, the problem can persist.


2. Hereditary Factors (Male Pattern Baldness)


Androgenetic alopecia, commonly known as male pattern baldness, is the most frequent cause of hair loss in men. This condition is influenced by genetics and hormonal changes, particularly an increased sensitivity of hair follicles to DHT (dihydrotestosterone). Over time, DHT causes hair follicles to shrink, leading to thinning hair and eventual loss.


3. Hormonal Imbalances


Hormonal changes, particularly in testosterone and DHT levels, can directly affect hair growth. Additionally, imbalances in thyroid hormones may also contribute to hair thinning or shedding. These imbalances may be linked to ageing, underlying health conditions, or lifestyle factors.


4. Lifestyle Factors


Poor lifestyle choices such as a nutrient-deficient diet, lack of sleep, smoking, and excessive alcohol consumption can contribute to hair loss. Hair needs the right nutrients and healthy circulation to grow, and habits that compromise overall health can weaken hair follicles and lead to thinning or shedding.

The Role of Genetics in Male Hair Loss

Genetics is one of the most significant factors contributing to hair loss in men, particularly in cases of androgenetic alopecia, also known as male pattern baldness. This hereditary condition is passed down through families and is primarily influenced by the body's sensitivity to DHT (dihydrotestosterone), a hormone derived from testosterone.


In men with androgenetic alopecia, hair follicles become increasingly sensitive to DHT over time. This sensitivity causes the hair follicles to shrink, producing thinner and shorter hair strands until, eventually, the follicles stop producing hair altogether. This process usually starts at the temples and the crown of the head, creating the characteristic pattern of male baldness.


If you have a family history of male pattern baldness, you are more likely to experience hair loss yourself. However, the onset and severity of hair loss can vary greatly from person to person. Some men may notice hair thinning in their early 20s, while others may not experience significant loss until later in life.

Can Hormonal Imbalances Cause Hair Loss?

Several key hormones influence hair growth, and when these hormones become unbalanced, it can lead to thinning hair or increased shedding. Here’s how specific hormones impact hair health:

  • DHT (Dihydrotestosterone): In men with androgenetic alopecia, hair follicles become increasingly sensitive to DHT. Over time, DHT binds to hair follicles, causing them to shrink.

  • Testosterone: Testosterone deficiency may lead to thinning hair or a reduction in hair density, particularly when combined with elevated DHT levels. Balancing testosterone levels is essential for maintaining healthy hair.

  • Thyroid Hormones: The thyroid gland produces hormones that regulate the body’s metabolism, and both hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid) can cause hair thinning or shedding.


Hormonal imbalances can occur due to a variety of factors, including age, chronic stress, or underlying medical conditions. Identifying these imbalances early is crucial in preventing further hair loss.


A Male Hair Loss Blood Test from One Day Tests can help you pinpoint any hormonal issues, such as elevated DHT or imbalanced testosterone, allowing you to take control of your hair health and seek appropriate treatments.
