3. If approved, you receive a REMPE 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 — present it at any pharmacy in the EU to collect your medication.

Who qualifies for selenium supplementation

Our EU-licensed doctors assess each case individually to determine if selenium supplementation is appropriate for you. They look for specific indicators in your medical history and symptoms, particularly those related to thyroid dysfunction and associated hair loss. Factors like a diagnosed thyroid condition (hypothyroidism or hyperthyroidism), symptoms of selenium deficiency, and other contributing factors to hair loss are considered. The doctor ensures that selenium supplementation aligns with your overall health profile and does not conflict with existing medications or conditions. It's about finding the right solution for your unique needs.

What selenium actually does (and doesn't do) for thyroid and hair

Selenium is an essential trace element crucial for optimal thyroid function. It helps your thyroid gland produce and convert thyroid hormones, specifically converting T4 (thyroxine) into T3 (triiodothyronine), the active form your body uses. This process is vital for regulating metabolism and supporting the health of hair follicles. Selenium also acts as a powerful antioxidant, protecting the thyroid gland from oxidative stress that can damage its cells. When thyroid function is optimal, the hair growth cycle can normalise, potentially reducing hair shedding and promoting healthier hair growth.

What selenium doesn't do is serve as a magic bullet for all hair loss. While it supports thyroid health, and thyroid issues can cause hair loss, selenium won't fix hair loss from other causes like male pattern baldness, alopecia areata, or nutritional deficiencies unrelated to thyroid function. Realistic timelines for seeing improvements in hair health, when linked to thyroid function and selenium, can vary, often taking several months as hair growth is a slow cycle.

Side effects and when to stop selenium

While generally safe when taken at recommended doses, excessive selenium intake can lead to adverse effects, a condition known as selenosis. Symptoms of selenosis can include hair loss, brittle nails, gastrointestinal issues, skin rashes, fatigue, and nerve damage. It's crucial to follow your doctor's dosage instructions precisely. You should stop taking selenium and consult your doctor if you experience any of these symptoms. Always inform your doctor about any other supplements or medications you are taking to avoid potential interactions. Medical honesty is key to safe and effective treatment.
