Blood Tests for Hair Loss: Understanding Which Panels to Request

Struggling with hair loss and wondering if blood tests can help? Yes, they can. Identifying the root cause of hair thinning or shedding is often the first step to effective treatment. At Hi-Doctor, you can get an online consultation with an EU-licensed doctor who understands these complex issues. For just €25, our doctors review your case and, if appropriate, issue a prescription for clinically proven hair loss treatments within 24 hours. This REMPE electronic prescription is valid at any pharmacy across the EU, making it easy and fast to get the medication you need.

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 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 treatment

Our EU-licensed doctors assess each case individually to determine the most appropriate treatment for your hair loss. They look for specific patterns of hair loss, such as androgenetic alopecia (male or female pattern baldness), and consider your overall health, medical history, and any existing blood test results. Treatments like Finasteride, Minoxidil, or Dutasteride are typically considered for adults experiencing genetic hair loss. The doctor ensures there are no contraindications and that the chosen treatment aligns with your health profile and needs.

What hair loss treatments actually do (and don't do)

Medications like Finasteride and Dutasteride work by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), a hormone that shrinks hair follicles in genetically predisposed individuals. Minoxidil, whether oral or topical, acts as a vasodilator, improving blood flow to hair follicles and extending the hair growth phase. These treatments aim to slow down hair loss, stimulate new growth, and improve hair density. They do not, however, cure the underlying genetic predisposition, meaning consistent use is often necessary to maintain results. Expect to see initial improvements, such as reduced shedding, within 1-3 months, with more significant regrowth visible after 4-6 months of continuous use. Full results can take 9-12 months.

Side effects and when to stop

Like all medications, hair loss treatments can have side effects. Finasteride and Dutasteride may cause sexual side effects such as decreased libido or erectile dysfunction in a small percentage of men. Oral Minoxidil can lead to changes in blood pressure or unwanted hair growth in other body areas. Topical Minoxidil may cause scalp irritation. Our doctors will discuss potential side effects specific to your prescribed treatment during your consultation. It's crucial to inform your doctor if you experience any concerning or severe side effects, as they may advise adjusting your dosage or discontinuing the treatment. Medical honesty builds trust, and your safety is our priority.
