Intermittent Fasting and Hair Loss: What You Need to Know

Experiencing hair loss can be distressing, especially when you're trying to improve your health through practices like intermittent fasting. If you're looking for an effective solution, you can get a prescription for clinically proven hair loss medication online from an EU-licensed doctor. Hi-Doctor offers a swift, secure, and affordable way to get your prescription: a €25 online consultation, a REMPE electronic prescription in under 24 hours if appropriate, valid at any pharmacy in the EU.

How it works — get your hair loss medication 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 decides the treatment is not appropriate, 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 medication

Our EU-licensed doctors assess each case individually. They look for specific criteria to determine if treatments like oral or topical Finasteride, Minoxidil, or Dutasteride are appropriate for you. Generally, these treatments are for adult men and women experiencing androgenetic alopecia (pattern hair loss). The doctor will review your medical history, current health conditions, and previous treatments to ensure the medication is safe and effective for you. Certain contraindications, such as pregnancy, breastfeeding, or specific liver conditions, may mean these treatments are not suitable.

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

Hair loss medications primarily work by targeting the underlying causes of hair thinning and loss. For example, Finasteride and Dutasteride reduce the production of DHT, a hormone linked to hair loss, thus slowing down or even reversing the process. Minoxidil, whether oral or topical, works by widening blood vessels and stimulating hair follicles, promoting regrowth. It's important to understand that these medications require consistent use and results are not immediate; typically, you'll see improvements within 3-6 months. They don't offer a permanent cure, and stopping treatment usually leads to reversal of benefits. They are most effective for preventing further loss and stimulating regrowth in areas where follicles are still active, but they won't bring back hair in completely bald areas.

Side effects and when to stop

Like all medications, hair loss treatments can have side effects. Common side effects for Finasteride and Dutasteride can include sexual dysfunction (e.g., decreased libido, erectile dysfunction), though these are often mild and reversible. Minoxidil can cause scalp irritation (itching, dryness) when applied topically, or more systemic effects like increased heart rate or fluid retention with oral administration. It's crucial to follow your doctor's instructions carefully. If you experience severe side effects, allergic reactions, or any concerning symptoms, you should stop the medication immediately and consult your doctor through the Hi-Doctor platform. Your doctor will provide full details on potential side effects and what to look out for.
