4. Print the PDF or show it on your phone — present it at any pharmacy in the EU to collect your medication.

Who qualifies for DHT blockers

When you complete your medical questionnaire, the doctor looks for specific criteria to ensure DHT blockers are safe and effective for you. Generally, DHT blockers like finasteride and dutasteride are prescribed for men experiencing androgenetic alopecia (male pattern baldness). These medications are typically not recommended for women, especially those who are pregnant or may become pregnant, due to potential risks. The doctor will also consider your medical history, current medications, and any pre-existing conditions to determine if finasteride or dutasteride is appropriate for your specific case.

What DHT blockers actually do (and don't do)

DHT blockers work by targeting dihydrotestosterone (DHT), a hormone that plays a key role in hair loss. Specifically, they inhibit the enzyme 5-alpha-reductase, which converts testosterone into DHT. By lowering DHT levels in the scalp, these medications can:

• Slow down or stop hair loss: They prevent DHT from shrinking your hair follicles.
• Promote regrowth: For some, they can lead to new hair growth, often appearing as thicker, healthier strands.
• Improve hair density: Existing hair may become thicker and stronger.

It's important to understand that DHT blockers do not cure baldness permanently. They manage the condition. You need to take them consistently to maintain results. Visible improvements usually take 3-6 months to appear, with full effects often seen after 12 months of continuous use. They are most effective for mild to moderate hair loss and may not restore hair in areas that have been completely bald for a long time.

Side effects and when to stop

Like all medications, DHT blockers can have side effects. For finasteride and dutasteride, these can include sexual side effects such as decreased libido, erectile dysfunction, and ejaculatory problems in a small percentage of men. These are often reversible upon stopping the medication. Other potential side effects include breast tenderness or enlargement. If you experience any severe or persistent side effects, or if you are concerned about any symptoms, you should stop the medication and consult a doctor immediately.
