Are you looking for a hair loss treatment prescription online in the EU? You've come to the right place. Hair loss, particularly androgenetic alopecia, is often linked to hormonal factors. Here's how you can get an EU-licensed doctor's prescription for effective treatments like finasteride or dutasteride online, quickly and safely. Our online consultation costs just €45 every 90 days (cancel anytime) or €35 one-off, and if approved, you'll receive a valid EU prescription within 24 hours, accepted at any pharmacy across the EU.

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

  1. Fill out our online medical questionnaire (takes 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 determines the treatment is not appropriate, your fee is refunded automatically — you pay nothing.
  3. If approved, you receive a valid electronic prescription (a downloadable 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 medication.

Who qualifies for hair loss treatments like finasteride or dutasteride?

Our EU-licensed doctors look for specific criteria to ensure these treatments are safe and effective for you. Generally, eligibility for medications like finasteride or dutasteride depends on the type and cause of your hair loss, your medical history, and any potential contraindications. These medications are primarily used for androgenetic alopecia (male or female pattern baldness), where DHT plays a significant role. The doctor will assess your symptoms, medical background, and any other medications you are taking to determine if these treatments are appropriate for your individual case.

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

Finasteride and dutasteride are oral medications that work by inhibiting the enzyme 5-alpha reductase, which is responsible for converting testosterone into dihydrotestosterone (DHT). DHT is a key hormone in androgenetic alopecia, causing hair follicles to miniaturize and eventually stop producing hair. By reducing DHT levels, these medications can slow down or even reverse hair loss, promoting regrowth of thicker hair. It's important to understand that results are not immediate; it typically takes 3-6 months to see noticeable improvements, and consistent use is necessary to maintain benefits. They do not treat all types of hair loss, only those linked to DHT sensitivity.

Side effects and when to stop

Like all medications, finasteride and dutasteride can have side effects. Common, but less frequent, side effects may include sexual dysfunction (e.g., decreased libido, erectile dysfunction) or mood changes. These are usually reversible upon discontinuation of the medication. More serious side effects are rare. Your doctor will discuss potential risks during your consultation. You should stop taking the medication and consult a doctor immediately if you experience persistent or severe side effects, or any signs of an allergic reaction.
