Who qualifies for hair loss treatment?

Our EU-licensed doctors assess your medical history, current health, and specific hair loss pattern to determine if minoxidil, finasteride, or dutasteride is appropriate for you. They look for:

• Type of Hair Loss: Primarily male pattern baldness (androgenetic alopecia).
• Overall Health: Any pre-existing conditions that might contraindicate these medications.
• Medication History: Possible interactions with other drugs you are taking.

Contraindications include certain heart conditions for minoxidil, and for finasteride/dutasteride, these are generally not prescribed for women, especially those who are pregnant or may become pregnant, due to risks of birth defects.

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

Hair loss treatments aim to slow down hair loss and stimulate new growth. Here's a quick overview:

• Minoxidil: A topical solution that works by widening blood vessels in the scalp, increasing blood flow to hair follicles. This can stimulate dormant follicles and prolong the growth phase of hair. You typically see results within 3-6 months.
• Finasteride: An oral medication that inhibits the enzyme 5-alpha reductase, reducing the conversion of testosterone to dihydrotestosterone (DHT). DHT is a key hormone in male pattern baldness. By lowering DHT, finasteride can halt hair loss and promote regrowth. Results often appear after 6-12 months of consistent use.
• Dutasteride: Also an oral medication, dutasteride is a more potent inhibitor of 5-alpha reductase than finasteride, blocking both type 1 and type 2 isoforms. This leads to a greater reduction in DHT levels and can be more effective for some individuals, though potential side effects may be more pronounced.

These treatments work best for ongoing hair loss, not for sudden, unexplained hair shedding. They require consistent use to maintain results.

Side effects and when to stop

It's important to be aware of potential side effects, though many are mild and temporary. Medical honesty builds trust, and knowing what to expect reduces anxiety.

Minoxidil Side Effects:

• Initial Shedding: Common in the first few weeks, a sign the treatment is working. New, healthier hairs are pushing out older ones.
• Scalp Irritation: Redness, itching, or dryness can occur.
• Unwanted Hair Growth: Rare, but can happen if the product spreads to other areas.
• Dizziness/Lightheadedness: If minoxidil is absorbed systemically, it can cause these. Stop use and consult a doctor if this occurs.

Finasteride/Dutasteride Side Effects:

• Sexual Side Effects: Decreased libido, erectile dysfunction, or reduced ejaculate volume. These are usually reversible upon stopping the medication.
• Mood Changes: Rare reports of depression or anxiety. Monitor your mental health.
• Breast Tenderness/Enlargement (Gynecomastia): Less common, due to hormonal changes.

When to seek medical attention: While many side effects are manageable, consult a healthcare professional immediately if you experience severe allergic reactions (rash, itching, swelling, trouble breathing), chest pain, heart palpitations, significant depression, or persistent sexual side effects.
