Who qualifies for Finasteride

Our EU-licensed doctors review each case individually to determine if Finasteride is a safe and appropriate treatment for you. They look for specific criteria:

  • Diagnosis of androgenetic alopecia: Finasteride is primarily for male pattern baldness.
  • Medical history: The doctor assesses any pre-existing conditions or medications that might interact with Finasteride.
  • Age and gender: Finasteride is generally prescribed for adult men. It is not approved for use in women or children.
  • Contraindications: Conditions like liver disease or hypersensitivity to Finasteride are important considerations.

The doctor's priority is your safety and the effectiveness of the treatment. If Finasteride is not suitable, they will explain why.

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.

What Finasteride actually does (and doesn't do)

Finasteride is a medication designed to treat male pattern baldness (androgenetic alopecia). It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is a key hormone responsible for shrinking hair follicles and causing hair loss.

  • What it does: Finasteride lowers DHT levels, which can slow down hair loss, and in some cases, promote hair regrowth. Many users experience stabilization of their hair loss.
  • Realistic timelines: You typically need to take Finasteride for 3–6 months to see initial results, with maximum benefits appearing after 1–2 years of consistent use.
  • Limitations: Finasteride is effective only as long as you continue to take it. Hair loss will likely resume if you stop the medication. It's not a cure for baldness, but a management strategy.

Side effects and when to stop

Like all medications, Finasteride can have side effects. Most are mild and reversible, but it's important to be aware of them:

  • Common side effects: These may include decreased libido, erectile dysfunction, and ejaculatory disorders. These are typically mild and often resolve with continued use or upon stopping the medication.
  • Less common side effects: Breast tenderness or enlargement (gynecomastia), and depression have been reported.
  • Red flags: Seek immediate medical attention if you experience mood changes, breast lumps, pain, nipple discharge, or any severe allergic reaction.

Always discuss any concerns about side effects with your doctor. They can advise whether to continue treatment, adjust the dosage, or consider alternative options.
