1. Do I need a letter from a psychiatrist or counselor before starting hormone therapy?
Yes. At HEALOR®, we require a letter of support from a licensed psychiatrist or counselor before initiating feminizing or masculinizing hormone therapy.
Hormone therapy can cause irreversible physical and psychological changes, and this requirement ensures patient safety and informed consent. This policy is also in compliance with Nevada state regulations. Requirements may vary by state, so always confirm with your medical provider.

3. Will I have more skin problems after starting hormone therapy?
Possibly. Testosterone therapy increases sebum (oil) production, which can make skin more oily and lead to acne or acne flares. This is common early in treatment and can usually be managed with skincare adjustments or medications.

4. How much scalp hair will I lose on testosterone therapy?
Scalp hair loss varies widely and depends on genetic sensitivity to dihydrotestosterone (DHT).
- Higher testosterone doses may accelerate male-pattern baldness
- At HEALOR®, we often prescribe custom topical formulations containing finasteride to block DHT locally
- Oral finasteride is generally avoided due to the risk of persistent sexual side effects

6. When will my voice deepen on testosterone?
Voice deepening typically begins between 6–12 months after starting testosterone and is irreversible. The timeline varies based on dose, genetics, and age.
7. When will I notice breast growth with feminizing hormone therapy?
Breast development depends on:
- Age at initiation
- Estrogen levels
- Use of effective anti-androgens
Among anti-androgens, bicalutamide has shown greater breast development compared to spironolactone in small studies. However:
- Bicalutamide may elevate liver enzymes
- It should not be used in patients with liver disease
- Requires close lab monitoring
