Who qualifies for Finasteride

Our EU-licensed doctors individually review each case to determine if Finasteride is appropriate for you. They look for specific criteria, primarily for men experiencing male pattern baldness (androgenetic alopecia). Finasteride works by targeting the hormonal causes of hair loss. Contraindications include women (especially those who are pregnant or planning to become pregnant) and individuals with certain liver conditions or allergies to Finasteride. The doctor assesses your medical history and current health to ensure your safety and the treatment's effectiveness.

What Finasteride actually does (and doesn't do)

Finasteride is an oral medication that works by blocking the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is a main culprit in male pattern baldness, causing hair follicles to shrink and eventually stop producing hair. By reducing DHT levels, Finasteride can slow down or stop hair loss and, in many cases, promote new hair growth. It doesn't cure baldness, but it effectively manages the condition. You typically see results within 3-6 months, with full effects often appearing after 12 months of consistent use. Finasteride is most effective for hair loss at the crown and mid-scalp, and less so for receding hairlines. It must be taken consistently to maintain its benefits; if you stop, hair loss will likely resume.

Noticing changes in your hair?

An EU-licensed doctor can privately review your case and decide whether a hair-growth treatment is appropriate for you. Online consultation for 45 € every 90 days or 35 € one-off, reply within 24 h.

Side effects and when to stop

Like all medications, Finasteride can have side effects, though they are generally mild and uncommon. The most frequently reported side effects include sexual dysfunction (such as decreased libido, erectile dysfunction, or ejaculation disorders), which usually resolve after stopping the medication. Other rare side effects can include breast tenderness or enlargement, skin rash, or allergic reactions. It is crucial to stop taking Finasteride and consult a doctor immediately if you experience any severe symptoms, such as chest pain, lumps in the breast, or significant mood changes. Our EU-licensed doctors will discuss these risks with you during your online consultation and monitor your progress.
