Hair Loss Treatment & Hydration: The Connection You Need to Know

If you're looking to get a prescription for hair loss treatment online in the EU, you've come to the right place. Hi-Doctor connects you with EU-licensed doctors who can assess your case and, if appropriate, prescribe medications like Finasteride or Minoxidil. The online consultation is just €25, and your prescription is issued within 24 hours, valid at any pharmacy across the EU. No risk — if the doctor says no, you get your money back.

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

  1. Fill the online medical questionnaire (2–3 minutes) and pay the €25 consultation fee.
  2. A licensed EU doctor reviews your case in private. If the doctor determines the treatment is NOT appropriate for you, your €25 is refunded automatically — no risk.
  3. If approved, you receive a REMPE 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 — present it at any pharmacy in the EU to collect the medication.

Who qualifies for hair loss treatment

Our EU-licensed doctors individually review every case to determine if hair loss treatment is appropriate for you. They will look for factors such as:

  • Type of hair loss: Typically male-pattern baldness (androgenetic alopecia) or female-pattern hair loss.
  • Medical history: Any pre-existing conditions or medications that might interact with hair loss treatments.
  • Age: Most treatments are for adults.
  • Overall health: Ensuring you are healthy enough to take the medication.

Contraindications will be carefully considered, and if the doctor determines the treatment is not suitable, your consultation fee will be refunded.

What hair loss treatment actually does (and doesn't do)

Hair loss treatments like Finasteride and Minoxidil work through different mechanisms to combat hair thinning and promote regrowth.

  • Finasteride: This oral medication works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is a key hormone responsible for shrinking hair follicles in genetically susceptible individuals. By reducing DHT levels, Finasteride can slow down hair loss and, in many cases, promote regrowth of finer hairs. It primarily targets the crown and mid-scalp.
  • Minoxidil: Available as a topical solution or foam, Minoxidil is a vasodilator that is believed to work by increasing blood flow to the hair follicles, extending the anagen (growth) phase of the hair cycle, and enlarging miniaturized follicles. It can be used for various types of hair loss and often shows results on the crown and vertex.

It's important to have realistic expectations. These treatments aim to slow or reverse hair loss and promote regrowth, but they are not a cure. Consistent use is required to maintain results, and significant improvements typically take several months to become noticeable.

Side effects and when to stop

Like all medications, hair loss treatments can have side effects. Your doctor will discuss these with you during the review process.

  • Finasteride: Potential side effects include sexual dysfunction (decreased libido, erectile dysfunction), ejaculatory disorders, and in rare cases, mood changes. Most side effects are reversible upon stopping the medication.
  • Minoxidil: Common side effects include scalp irritation, itching, dryness, and unwanted hair growth on other parts of the body if the product drips.

You should stop treatment and consult a doctor if you experience severe allergic reactions, chest pain, rapid heartbeat, dizziness, or swelling of the hands or feet. Your Hi-Doctor account provides a private, RGPD-compliant chat for any concerns you may have.
