People experiencing hair loss are often prescribed DHT blockers supplements as treatments. 

Dihydrotestosterone (DHT) is a hormone derived from the male hormone Testosterone, which has been associated with hair loss.

As a result, the market for DHT-blocking supplements has gained popularity, as many seek to mitigate hair loss and promote hair growth. 

The following article explores the ingredients of DHT blocker and their potential benefits.

Role of DHT blocking supplement

Dihydrotestosterone (DHT) binds to hair follicles, leading to their miniaturization and a shorter hair growth cycle. 

Over time, this process can contribute to hair thinning and eventual hair loss.

DHT-blocking supplements are formulated with natural ingredients that aim to reduce the production or activity of DHT in the body. 

By inhibiting the production of this hormone or interfering with its binding to hair follicles, these supplements seek to slow down or prevent hair loss.

Ingredients of DHT blocking Supplements

The ingredients in DHT supplements show their unique properties to block DHT and prevent hair loss. 

The most common supplements that block DHT include the following ingredients, 

Saw Palmetto

Saw palmetto is a herbal supplement that works as a DHT blocker to help prevent hair loss

It inhibits the enzyme 5-alpha reductase, which is responsible for converting Testosterone into DHT. 

A small study showed positive outcomes for patients treated with topical saw palmetto. 

After four months of therapy, about half of the 25 individuals had a rise in hair count of 11.9%.

Pumpkin seed oil

The pumpkin seed oil contains compounds that may help block the production of DHT, a hormone associated with hair loss.

It contains phytosterols and fatty acids that block the activity of 5-alpha reductase enzymes and restrict DHT production. 

A 2019 study showed positive results of using pumpkin seed oil to prevent hair loss caused by Male Pattern Baldness and promote hair growth.

However, more evidence is needed to fully understand pumpkin seed oil’s specific mechanisms and effectiveness as a DHT blocker for preventing hair loss.

Nettle root

Nettle root is part of the stinging nettle plant, which contains components that block the 5-alpha reductase enzyme activity. 

A 2015 study exploring nettle root’s effects on preventing Benign Prostatic Hyperplasia showed that it works as a DHT blocker. 

Benign Prostatic Hyperplasia (BPH) is a condition that causes prostate gland enlargement in men. It can cause urinary symptoms such as frequent urination, weak urine flow, difficulty initiating or maintaining urination, and incomplete bladder emptying.

Hence, it restricts the production of DHT to aid in preventing hair fall. 

Additionally, nettle root promotes blood circulation, provides nutrients to the scalp, and strengthens hair follicles, further supporting healthy hair growth and reducing hair loss.

Side effects of DHT blocker supplements

DHT blocker supplements are generally considered safe.

But they might have side effects which may include:

  • Digestive disturbances such as stomach upset, diarrhea or nausea can occur in some individuals
  • DHT blocker supplements may influence hormonal balance, which can lead to unintended effects
  • Some people may be allergic to some ingredients present in supplements that block DHT and can experience mild skin rashes to severe respiratory difficulties
  • DHT blocker supplements containing saw palmetto may interact with certain medications to cause side effects

While DHT blocker supplements can prevent hair loss, they might not work for everyone. 

However, DHT blocker medicines, such as Finasteride or Dutasteride, are prescription medications specifically formulated and tested for efficacy and safety. 

Doctors prescribe them, ensuring proper dosage and monitoring for potential side effects. 

Finasteride, a DHT blocker medicine, is FDA-approved to treat Male Pattern Baldness and Benign Prostatic Hyperplasia in men.

They are prescribed off-label by doctors to treat other conditions as well.

If not taken properly, the medicine can cause side effects. Do not take the DHT blocker medicine without consulting your healthcare provider.


DHT blockers are often prescribed as natural remedies for conditions related to excess DHT, such as hair loss. 

While these supplements may offer potential benefits, it is vital to take them with caution. 

Unlike prescription DHT blocker medicines, supplements’ quality, potency, and effectiveness can vary significantly. 

The lack of research on supplements means that their efficacy may not be adequately supported. 

If someone has advised you to take DHT supplements, it is always advisable to consult with your doctor before taking the supplements.
