How it works: get your hair loss treatment prescription in 4 steps

  1. Fill out a short online medical questionnaire (2–3 minutes) and pay the consultation fee of €45 every 90 days or €35 one-off.
  2. A licensed EU doctor reviews your case privately. If the doctor decides the treatment is not appropriate, your payment is refunded automatically, so there is no risk.
  3. If approved, you receive a valid electronic prescription (PDF file) in your Hi-Doctor account and by email within 24 hours.
  4. Print the PDF or show it on your phone and present it at any pharmacy in the EU to collect your finasteride or dutasteride medication.

Who qualifies for finasteride or dutasteride

Our EU-licensed doctors carefully evaluate each case to ensure finasteride or dutasteride is safe and appropriate for you. Generally, these medications are prescribed for adult males experiencing androgenetic alopecia (male pattern baldness). The doctor will look for:

  • A clear diagnosis of male pattern hair loss.
  • No contraindications such as liver disease, prostate conditions, or allergic reactions to the medication.
  • No current use of other medications that may interact negatively.

Women, especially those who are pregnant or planning to become pregnant, are generally not candidates for oral finasteride or dutasteride due to potential risks. Your doctor will review your full medical history to determine eligibility.

What finasteride and dutasteride actually do (and don't do)

Finasteride and dutasteride are 5-alpha-reductase inhibitors. They work by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone primarily responsible for shrinking hair follicles in genetically predisposed individuals. By reducing DHT levels, these medications can slow down hair loss and, in many cases, promote regrowth of existing hair.

What they do:

  • Slow down or stop further hair loss.
  • Thicken existing hair and promote new hair growth.
  • Improve hair density over time.

What they don't do:

  • Cure baldness instantly. Results require consistent use over several months.
  • Work for all types of hair loss (e.g., alopecia areata, telogen effluvium).
  • Guarantee a full head of hair for everyone. Individual results vary.

Expect to see initial results within 3-6 months of consistent use, with more significant improvements often visible after 12 months. Continued use is necessary to maintain benefits.

Side effects and when to stop

Like all medications, finasteride and dutasteride can have side effects, though they are generally well-tolerated. Common side effects can include decreased libido, erectile dysfunction, and breast tenderness. These are typically mild and reversible upon stopping the medication.

Red flags requiring immediate medical attention:

  • Severe allergic reactions (rash, itching, swelling, severe dizziness, trouble breathing).
  • Changes in breast tissue, such as lumps, pain, or nipple discharge (which could be signs of male breast cancer).
  • Persistent mood changes, including depression.

Always discuss any concerns with your doctor. If side effects are bothersome or severe, your doctor may recommend adjusting the dose or discontinuing treatment.
