Hair shedding is a normal and often temporary response to hormonal changes. Starting testosterone replacement therapy (TRT) can sometimes accelerate this process, especially in men who are genetically prone to male pattern baldness (MPB).
Shedding vs. Balding
Many patients experience shedding during the first few months of TRT. This doesn’t always lead to permanent hair loss.
Shedding is often a short-term adjustment phase.
Balding (MPB) is genetic and progressive, primarily driven by DHT (dihydrotestosterone), a byproduct of testosterone.
Key Facts
50% of men will experience MPB by age 50.
TRT doesn’t cause baldness but may accelerate the timeline in genetically predisposed individuals.
MPB typically begins at the temples, crown, or receding hairline.
If you have a family history, you’re more likely to notice progression.
What Hormn Recommends
We do not prescribe medications like finasteride (a DHT-blocker), due to:
Significant risk of side effects
Low libido, erectile dysfunction, and even symptoms resembling low testosterone
It works by lowering DHT, a hormone that plays a key role in male health
What You Can Do
1. Monitor Shedding
Mild shedding early in treatment is usually temporary.
If it stabilises after a few months, it’s not likely MPB-related.
2. Track Patterns
Take monthly photos of hairline and crown.
Note changes in density and shape—not just loose hairs.
3. Hair Care Practices
Avoid harsh shampoos or aggressive towel-drying.
Use gentle, sulfate-free shampoos with ingredients like ketoconazole if concerned.
4. Consider Lifestyle Factors
Ensure a high-protein diet, manage stress, sleep well, and get regular exercise—all of which support hair health
TRT may increase shedding or accelerate MPB in men who are genetically predisposed. Shedding alone is common and often temporary.
We don’t recommend DHT-blocking drugs due to their side effects.
If you're concerned, focus on tracking changes and optimising overall health.
