Keto Diet and Hair Loss: Understanding the Connection

Experiencing hair loss while on a Keto diet is a common concern for many. If you're looking for solutions, including medication like minoxidil or finasteride, an EU-licensed doctor can help. Hi-Doctor provides a convenient, online consultation for just €45 every 90 days (cancel anytime) or €35 one-off. If the doctor finds treatment appropriate, you receive an electronic prescription in under 24 hours, valid at any pharmacy in 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 consultation fee of €45 every 90 days or €35 one-off.
  2. A licensed EU doctor reviews your case in private. 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 medication.

Who qualifies for hair loss treatment

When you consult with an EU-licensed doctor through Hi-Doctor, they carefully assess your individual case to determine if medication for hair loss, such as minoxidil or finasteride, is appropriate for you. They look for specific criteria, including:

  • Your medical history and current health status.
  • The specific type and pattern of your hair loss.
  • Any underlying conditions or medications that might be contributing to hair loss.
  • Potential contraindications for specific treatments.

The doctor's primary goal is to ensure your safety and that the treatment is both effective and suitable for your needs.

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

Medications like minoxidil and finasteride work in different ways to combat hair loss. Minoxidil, a topical solution, is believed to widen blood vessels, which improves blood flow to hair follicles and stimulates growth. Finasteride, an oral medication, works by blocking the production of a hormone called DHT, which is a major cause of male pattern baldness. These treatments can slow down hair loss and, in some cases, promote new hair growth. However, they do not offer instant results; it typically takes several months of consistent use to see noticeable improvements. They are most effective for specific types of hair loss and do not cure underlying conditions like nutrient deficiencies from a restrictive diet.

Side effects and when to stop

Like all medications, hair loss treatments can have side effects. Common side effects for minoxidil include scalp irritation, itching, or unwanted facial hair growth. Finasteride can cause sexual side effects in a small percentage of men, such as decreased libido or erectile dysfunction. It's crucial to discuss all potential side effects with your Hi-Doctor physician. If you experience severe or persistent side effects, or if your hair loss worsens, you should stop the medication and consult your doctor immediately. Your doctor will advise you on the best course of action based on your individual response.
