Hair loss is a common concern for men and women alike, especially during middle age when hormonal fluctuations become more noticeable. A quick glance in the mirror or the sight of a few extra hairs on your pillow can prompt questions about what’s normal and what’s not. One particularly enduring question is this: Does testosterone cause hair loss?
The short answer is not as straightforward as it may seem. Testosterone does play a role in the process, but it’s part of a much more intricate biological mechanism involving another hormone called dihydrotestosterone (DHT) and genetic sensitivity. Here, we’ll examine the scientific relationship between testosterone and hair loss, dispel common myths, and highlight potential ways to support healthy hair naturally.
Understanding Testosterone and Its Functions
Testosterone is a key androgen hormone found in both men and women, although it’s more abundant in males. It’s vital for several bodily functions, including muscle development, fat distribution, libido, bone density, and the growth of facial and body hair. However, its role in scalp hair is where things become more complex.
While testosterone encourages the growth of body and facial hair, it indirectly influences scalp hair through its conversion to dihydrotestosterone (DHT). This derivative plays a significant role in triggering a type of hair loss known as androgenetic alopecia, but only in individuals with a genetic predisposition.
The Role of DHT in Hair Loss
DHT is produced when testosterone is converted by the enzyme 5-alpha reductase. This conversion primarily occurs in the skin, prostate, and hair follicles. Though DHT is necessary for certain developmental processes, its interaction with scalp follicles is often where trouble begins.
In individuals sensitive to DHT, the hormone binds to androgen receptors in the scalp’s hair follicles. Over time, this causes the follicles to shrink, a process known as follicle miniaturisation. The result is thinner hair, shorter growth cycles, and eventually, dormant follicles that no longer produce visible strands. This pattern is known as androgenetic alopecia and is the most common form of hair loss in both men and women.
Does Testosterone Cause Hair Loss?
Contrary to popular belief, having high levels of testosterone doesn’t automatically mean you’ll lose your hair. Studies have shown that total testosterone levels are not consistently higher in balding men compared to those with full heads of hair. The real issue lies in how efficiently testosterone is converted to DHT and, more importantly, how your follicles respond to that DHT.
Genetic sensitivity to DHT is the primary reason why some individuals experience hair thinning despite normal testosterone levels. This inherited trait determines whether or not your follicles are vulnerable to the shrinking effects of DHT.
The presence of testosterone or even DHT alone isn’t enough to trigger hair loss. It’s the combination of genetic vulnerability and prolonged exposure to DHT that results in follicular miniaturisation. Without the genetic component, DHT is unlikely to cause significant hair loss.
Interestingly, low testosterone can also contribute to hair thinning. Hormonal imbalances may disrupt the hair growth cycle and reduce the density and vitality of existing hair. This is particularly relevant during middle age when natural hormone levels begin to decline.

Rather than masking symptoms, GR-7 addresses the root causes of hair thinning through nutritional and topical care.
Conclusion
So, does testosterone cause hair loss? Not directly. The true culprits are DHT and your individual genetic makeup. Testosterone can influence the process through its conversion to DHT, but it’s the sensitivity of your follicles that ultimately determines whether or not you’ll experience hair thinning. By recognising these nuances and understanding the role of hormones, enzymes, and genetics, individuals can make more informed, proactive choices when it comes to managing their long-term hair health and preservation.
