What Are DHT Blockers and Do They Work?

What Is DHT

DHT, short for dihydrotestosterone, is a hormone derived from testosterone that plays a crucial role in hair growth and development in both men and women. However, elevated levels of DHT have been associated with hair loss and other health concerns. DHT blockers are substances that inhibit the conversion of testosterone to DHT. In this article, we explore what DHT blockers are, their mechanism of action, their effectiveness and potential benefits, as well as their safety and potential side effects.


What Is DHT?



DHT, or dihydrotestosterone, is a hormone derived from testosterone. It is a potent androgen that plays a major role in the development and maintenance of secondary sexual characteristics in both men and women. (1) DHT is synthesized from testosterone primarily in the prostate gland, hair follicles, and adrenal glands.


DHT is responsible for the development of male characteristics during puberty, such as facial and body hair growth, deepening of the voice, and the development of the prostate gland. In women, DHT contributes to the regulation of libido and the growth of pubic and underarm hair. (1)


While DHT has important physiological functions, elevated levels of DHT can lead to various health concerns. One of the most well-known effects of excess DHT is its association with male pattern baldness, also known as androgenetic alopecia. In individuals genetically predisposed to hair loss, DHT can bind to androgen receptors in hair follicles, causing them to shrink and produce thinner, shorter hair strands. Over time, this can result in hair loss and a receding hairline. (2)


Apart from hair loss, elevated levels of DHT have also been linked to benign prostatic hyperplasia (BPH), a condition characterized by an enlarged prostate gland, and can contribute to the development of acne, oily skin, and hirsutism (excessive hair growth) in certain areas of the body.


Understanding the role of DHT in various physiological processes is important when considering treatments or interventions aimed at managing conditions associated with DHT, such as hair loss or prostate-related issues.


What Are DHT Blockers?


DHT blockers, also known as DHT inhibitors, are substances that help prevent the conversion of testosterone into dihydrotestosterone. They work by inhibiting the enzyme 5-alpha-reductase, which is responsible for this conversion. (3) By reducing DHT levels, these blockers aim to slow down hair loss and potentially stimulate hair regrowth. While DHT blockers are commonly associated with treating hair loss, they can also have broader implications for conditions like benign prostatic hyperplasia (BPH) and androgenetic alopecia.


How Do DHT Blockers Work?


DHT blockers function by either blocking the 5-alpha-reductase enzyme or by reducing the binding of DHT to androgen receptors in the hair follicles. (3) By targeting these pathways, DHT blockers aim to interrupt the negative effects of DHT on hair follicles and promote a healthier hair growth cycle. However, it is important to note that DHT blockers primarily address the underlying cause of hair loss associated with DHT rather than other forms of hair loss caused by factors like nutrient deficiencies or autoimmune disorders.


Effectiveness of DHT Blockers


The effectiveness of DHT blockers can vary depending on various factors, such as the individual's genetic predisposition, the stage and severity of hair loss, and the specific DHT blocker used. While some individuals may experience noticeable improvements in hair growth, others may see minimal to no results. It is important to note that DHT blockers may be more effective for individuals experiencing androgenetic alopecia, the most common form of hair loss, compared to other types of hair loss. Results also vary based on the duration of treatment, as consistent use over several months may be necessary to observe significant changes.


DHT Blockers for Women


Hair loss is not solely a male concern, as many women also experience thinning hair and hair loss. DHT blockers can be beneficial for women as well, although the underlying causes of hair loss in women can vary. Women should consult with a healthcare professional or a dermatologist to determine the cause of their hair loss before considering DHT blockers, as hormonal imbalances and other factors may contribute to their hair loss. Additionally, women who are pregnant or breastfeeding should exercise caution and seek medical advice before using DHT blockers.


Are DHT Blockers Safe?


DHT blockers are generally considered safe when used as directed. However, like any medication or supplement, they may have potential side effects. Some common side effects associated with DHT blockers include:


  • Decreased libido
  • Erectile dysfunction
  • Breast tenderness
  • Scalp irritation


It is crucial to discuss the potential risks and side effects with a healthcare professional before starting any DHT blocker regimen. Regular monitoring and open communication with a medical professional can help identify any adverse effects early on.


Natural DHT Blockers

In addition to pharmaceutical DHT blockers, there are also natural alternatives available. Certain herbs and plant extracts are believed to possess DHT-blocking properties. Saw palmetto, pumpkin seed oil, pygeum, green tea extract, and stinging nettle root are some examples of natural DHT blockers. 


However, it is important to note that more research is still needed to verify the effectiveness of these herbs as natural DHT blockers. It is always advisable to consult with a healthcare professional before using natural DHT blockers, especially if you are taking any medications or have pre-existing health conditions.


Do DHT Blockers Work? 


There are many misconceptions surrounding the effectiveness of DHT blockers. Some people believe that DHT blockers can magically restore a full head of hair or that they work equally well for everyone. However, it is important to approach these claims with caution. While DHT blockers can be effective for some individuals, results vary depending on multiple factors. Additionally, it is crucial to have realistic expectations and understand that DHT blockers may slow down hair loss and promote hair regrowth to a certain extent, but they are unlikely to produce miraculous results overnight.


Healing of any kind generally takes time, patience, and commitment to the health protocol that is being followed. With consistent efforts, however, the body is more likely to heal over time. It is important to consult with your doctor for the best health advice and guidance as it relates to your particular situation.




DHT blockers have gained attention as potential treatments for hair loss in both men and women. They work by inhibiting the conversion of testosterone into DHT, a hormone associated with hair loss. They have also been used in some cases to support a healthy prostate.


While DHT blockers can be effective for some individuals, their effectiveness may vary, and they may come with potential side effects. It is essential to consult with a healthcare professional before starting any DHT blocker regimen and to consider a holistic approach to hair and prostate health, including a balanced diet, a healthy lifestyle, and addressing any underlying health issues. By understanding the mechanisms, potential risks, and benefits of DHT blockers, individuals can make informed decisions and take steps toward maintaining their health.
