What is DHT hormone? DHT hormone, short for Dihydrotestosterone, plays a major role in the development of male characteristics. It’s a byproduct of testosterone, and it helps shape many aspects of masculinity, starting as early as in the womb. For instance, the DHT hormone is responsible for the development of male genitalia, changes in facial and body hair, and deepening of the voice during puberty.

Although DHT is predominantly found in males, females also produce it—but in much smaller amounts.

What Happens When You Have Too Much or Too Little DHT Hormone?

Like many hormones, DHT hormone levels need to be well-balanced. Too much or too little can result in various health issues.

When DHT hormone is too low

Underdevelopment of sexual organs such as the penis, testes, and prostate
Enlargement of breast tissue due to hormonal imbalance
Increased fat accumulation
Higher risk of cardiovascular disease and prostate cancer

When DHT hormone is too high

One of the most common effects is hair loss, especially in men with a genetic predisposition.
Overproduction can accelerate DHT hormone hair loss, leading to male pattern baldness.

How Does DHT Hormone Cause Hair Loss?

The connection between DHT hormone and hair loss lies in the way DHT interacts with androgen receptors in hair follicles. Under normal conditions, hair growth follows a cycle: a growth phase lasting 2–6 years, followed by a resting phase of 1–4 months. But when DHT hormone binds to receptors in the scalp, it disrupts this cycle.

Here’s how:

DHT shortens the hair growth phase.
It extends the resting phase, causing new hair to take longer to emerge.
Over time, hair follicles shrink and produce thinner, weaker strands.
Eventually, the follicles may stop producing hair entirely.

If you’re genetically predisposed to DHT hormone hair loss, this process can happen faster and more severely, as your scalp may have more active androgen receptors.

How to Reduce DHT Hormone Naturally and Medically

If you’re dealing with DHT hormone hair loss, don’t worry—there are effective ways to manage it.

1. Medications for Hair Loss

There are two FDA-approved medications commonly used to combat hair loss caused by DHT:

Finasteride (for men only)

Finasteride works by inhibiting the conversion of testosterone into DHT, reducing DHT levels in the body by up to 60%. This helps slow down hair loss and can even promote regrowth. However, it may cause temporary side effects, such as decreased libido or sexual function. These typically resolve after discontinuation or with long-term use. Note: Finasteride is not recommended for women due to potential side effects and limited effectiveness.

Minoxidil (for both men and women)

Minoxidil doesn’t directly lower DHT hormone but works by widening blood vessels to improve blood flow to the scalp. This stimulates hair follicles, extends the hair growth phase, and helps reduce shedding.

2. Lifestyle Adjustments

Your daily habits can influence DHT hormone levels. Here’s how to help keep them in check:

Maintain a healthy weight
Exercise regularly
Quit smoking
Manage stress levels

These changes won’t just help with hair—they’ll also improve your overall hormone balance.

3. Hair-Friendly Supplements

Certain nutrients may naturally inhibit DHT hormone production and support healthier hair:

Zinc: Helps block the enzyme that converts testosterone into DHT
Biotin (Vitamin B7): Strengthens hair follicles and improves hair resilience against the effects of DHT

Managing DHT Hormone Hair Loss Is Possible

For men, DHT hormone hair loss is one of the leading causes of thinning hair and baldness. However, with consistent self-care, smart lifestyle choices, and the right medical advice, it’s entirely manageable. Whether you’re just noticing signs of hair loss or dealing with a long-term concern, understanding your DHT levels is a great place to start.

If you’re considering professional solutions like FUE (Follicular Unit Extraction) to restore your hairline, it’s helpful to first understand the treatment options, results, and FUE hair transplant cost involved.
