DHT (Dihydrotestosterone)

DHT is an androgen that, even in small amounts, may influence skin health, hair growth, and hormonal balance in women. Elevated levels could suggest conditions such as PCOS.

What It Measures

This test measures the concentration of dihydrotestosterone in your blood. DHT is the most biologically active androgen and reflects the conversion of testosterone by 5-alpha reductase activity in tissues.

Why It Matters

In women, elevated DHT could suggest androgen excess and may contribute to unwanted hair growth, acne, or hair thinning. Monitoring supports early identification of hormonal imbalances. Consult your healthcare provider.

When to Test

Testing may be recommended when investigating hair loss, prostate health concerns, signs of androgen excess, or when evaluating the effects of 5-alpha reductase inhibitor medications.

Symptoms

Low Levels

Some people may experience reduced body hair growth, delayed sexual development, or decreased libido when DHT levels are low. These symptoms could suggest insufficient androgen activity.

High Levels

Some people may experience accelerated hair thinning, acne, or oily skin when DHT levels are elevated. In men, high DHT could suggest increased prostate growth risk. Discuss concerns with your healthcare provider.

Lifestyle Tips

Regular exercise, a balanced diet rich in zinc and healthy fats, and stress management may support healthy androgen balance. Specific DHT-lowering interventions should only be discussed with your healthcare provider.

Frequently Asked Questions

Does DHT cause hair loss?
DHT may contribute to pattern hair loss in genetically predisposed individuals by shrinking hair follicles. Your healthcare provider can discuss treatment options.
What is the relationship between DHT and testosterone?
DHT is produced from testosterone by the enzyme 5-alpha reductase. It is several times more potent than testosterone at androgen receptors.
Can DHT levels be safely reduced?
Medications that inhibit 5-alpha reductase can lower DHT, but they may have side effects. Discuss benefits and risks with your healthcare provider.
