Understanding How DHT Blockers Help Regrow Hair
Hair loss is one of the most common concerns for both men and women, often linked to genetics, hormonal changes, and aging. Among the primary culprits is DHT (dihydrotestosterone), a hormone that plays a major role in androgenetic alopecia, the most common type of hair loss.
What is DHT and Why Does It Cause Hair Loss?
DHT is a derivative of testosterone. While it’s essential for certain bodily functions, excess DHT can bind to receptors in hair follicles, causing them to shrink over time. This process, called miniaturization, leads to:
• Thinner hair strands
• Shortened growth cycles
• Eventual follicle dormancy and hair loss
• Types of DHT in the Body
Systemic DHT (Circulating in the Bloodstream)
Produced when testosterone is converted into DHT by the enzyme 5-alpha reductase in various tissues (including the liver and prostate).
This form of DHT travels through the bloodstream and can affect hair follicles indirectly.
Localized DHT (In the Scalp and Hair Follicles)
DHT is also produced locally in the scalp by the same enzyme.
This localized DHT binds to androgen receptors in hair follicles, causing miniaturization (shrinking of follicles), which leads to thinning hair and eventual hair loss.
How Do DHT Blockers Work?
DHT blockers prevent this hormone from attaching to hair follicle receptors, reducing its damaging effect. By lowering DHT activity, follicles can recover and resume normal growth cycles.
There are two main forms of DHT blockers:
1. Oral DHT Blockers (Pills)
Brands like Advanced Trichology offer supplements that include natural DHT-blocking ingredients such as saw palmetto, pumpkin seed oil, and other botanicals. These work systemically to reduce DHT levels throughout the body.
2. Topical DHT Blockers
Companies like Keeps provide topical solutions that target the scalp directly. These treatments often combine DHT-blocking agents with other growth stimulants, ensuring localized action where it matters most.
The Science Behind Hair Regrowth
When DHT is blocked:
Follicles regain their size and function.
Hair enters the anagen phase (growth phase) for longer periods.
Combined with proper scalp care and nutrition, this can lead to visible regrowth over time.
Why DHT Blockers Work
Oral DHT Blockers (like those from Advanced Trichology) reduce systemic DHT levels throughout the body.

Topical DHT Blockers (like those from Keeps) target localized DHT in the scalp, preventing it from binding to follicle receptors.

By addressing both systemic and localized DHT, these treatments help stop hair loss and allow follicles to recover, promoting regrowth.
Potential Side Effects and Why Natural DHT Blockers Matter
Prescription DHT blockers like Finasteride are clinically proven but can come with side effects such as:
• Reduced libido
• Erectile dysfunction
• Hormonal imbalances in some users
• Nausea
These risks make natural DHT blockers an attractive alternative. Ingredients like saw palmetto, pumpkin seed oil, and green tea extract work to reduce DHT activity without significantly altering systemic hormone levels. While results may be slower compared to prescription drugs, natural options often provide a safer, long-term approach for those concerned about side effects.
Other Supportive Remedies
While DHT blockers are powerful, combining them with other treatments enhances results:
• Minoxidil – Stimulates blood flow and follicle activity.
• Scalp Treatments – Exfoliation and hydration improve absorption.
• Nutritional Support – Vitamins like biotin and zinc strengthen hair.

Final Thoughts
DHT blockers whether oral or topical address the root cause of androgenetic hair loss by preventing follicle miniaturization. Opting for natural sources can help minimize potential side effects while supporting overall scalp health and hair regrowth. If you start treatment early, it’s always better to choose natural options for a safer, long-term approach. Remember, consistency and a holistic routine including proper nutrition, scalp care, and stress management are key to achieving lasting results.
