12/17/2025

Key Takeaways

The DHT Connection: Hair loss during Testosterone Replacement Therapy (TRT) is primarily caused by the conversion of testosterone into Dihydrotestosterone (DHT).
Genetic Factors: Your genetic predisposition determines how sensitive your hair follicles are to hormonal shifts.
Proactive Care: Combining medical-grade topicals, oral DHT blockers, and PRP therapy offers the highest hair-preservation success rate.
Local Expertise: Patients in Brooklyn benefit from personalized protocols that account for diverse hair textures and urban environmental stressors.

Testosterone Replacement Therapy (TRT) is a transformative treatment for many men and women in Brooklyn, NY, aiming to optimize energy, mood, and physical performance. However, a common side effect of increased androgen levels is accelerated hair thinning. At Skin Glow Dermatology, Yelena Terushkin, PA-C, specializes in medical hair restoration strategies that allow you to enjoy the benefits of hormone optimization without sacrificing your hair.

Understanding Testosterone-Related Hair Loss and DHT

The biological link between testosterone and hair loss is the enzyme 5-alpha reductase. This enzyme is responsible for converting a portion of your testosterone into Dihydrotestosterone (DHT).

In individuals with a genetic sensitivity, DHT binds to receptors in the scalp, causing a process called “miniaturization.” During this process, the hair follicles shrink, produce thinner strands, and eventually stop growing altogether. This is why managing DHT is the cornerstone of any prevention strategy.

Clinical Procedures to Prevent Hair Loss While on Testosterone

For residents of Kings County looking for professional-grade results, we offer a tiered medical approach within our cosmetic dermatology department to stabilize the hair cycle and protect the scalp..

1. Medical DHT Blockers and Management

The most effective way to address hair loss at its source is to limit DHT production, whether systemic or localized.

Oral Medications: FDA-approved treatments such as Finasteride work by inhibiting the 5-alpha-reductase enzyme.
Topical Solutions: Custom-compounded formulas can deliver DHT blockers directly to the follicle, minimizing systemic absorption.
Hormonal Monitoring: Regular blood work at our Brooklyn office helps ensure your TRT dosage is optimized to reduce unnecessary DHT spikes.

2. Platelet-Rich Plasma (PRP) Therapy

PRP therapy is one of our most requested treatments for patients on TRT. It uses growth factors from your own blood to “jumpstart” follicles suppressed by hormones.

The Procedure: We draw a small amount of blood, spin it in a high-speed centrifuge, and inject the concentrated platelets into the scalp.
The Result: Increased blood flow and cellular repair that thickens existing hair and extends the growth phase.

3. Medical-Grade Microneedling

Microneedling creates controlled micro-channels in the scalp. This not only stimulates a healing response but also dramatically increases the absorption rate of prescribed topical treatments.

Frequently Asked Questions About Preventing Hair Loss

Will stopping testosterone regrow my hair?

If the hair follicles have only miniaturized, stopping or lowering your TRT dose may slow further loss. However, active regrowth usually requires clinical intervention, such as PRP or prescription topicals, to stimulate the follicle back into the growth phase.

How often should I get PRP for hair loss?

For most patients on testosterone therapy, we recommend an initial “loading phase” of 3 to 4 treatments spaced one month apart. Afterward, maintenance sessions every 6 to 12 months are typical to keep the follicles active.

Can hair loss from testosterone be reversed?

Yes, if caught in the early to middle stages. Once a follicle has completely scarred over—resulting in a smooth, shiny scalp area—it can no longer produce hair. Early intervention at our Brooklyn clinic is key.

Does testosterone cause hair loss if I have no family history of baldness?

Genetics plays the most significant role. If you lack the genetic sensitivity to DHT, you may not experience substantial thinning. However, some patients experience temporary “shedding” (Telogen Effluvium) due to the sudden shift in hormone levels when starting TRT.

Are there specific vitamins for hair health during hormone therapy?

Yes. We often recommend medical-grade supplements containing Biotin, Zinc, and Saw Palmetto. Managing the urban environment of Brooklyn—such as hard water and pollution—with clarifying scalp treatments also supports a healthy growth environment.

Does topical testosterone (gel) cause less hair loss than injections?

Not necessarily. Both delivery methods increase the total amount of testosterone in your body, which can be converted into DHT. The rate of conversion depends more on your individual metabolism and genetics than the method of administration.

Can I use Ketoconazole shampoo to block DHT?

Ketoconazole (Nizoral) has mild anti-androgen properties. While it is a helpful addition to a hair-care routine, it is rarely potent enough to counteract the significant hormonal changes associated with TRT on its own.
