Who qualifies for hair loss treatment

When you consult with a Hi-Doctor EU-licensed physician, they carefully assess your medical history and current health status to determine if Finasteride or Minoxidil is appropriate for you. Here's what the doctor looks for:

Finasteride eligibility and contraindications

Finasteride is primarily for male pattern baldness. It works by reducing the hormone DHT. The doctor will consider:

  • Age and Gender: Finasteride is generally prescribed for men. It is strictly contraindicated for women who are pregnant or may become pregnant, as it can cause birth defects in male fetuses. Women of childbearing age should also avoid handling crushed or broken tablets.
  • Liver Health: As Finasteride is processed by the liver, individuals with severe liver disease may not be suitable candidates.
  • Allergies: A known allergy to Finasteride or its components is a contraindication.
  • Medical History: The doctor will assess for any history of depression or sexual dysfunction, as these can be potential side effects.

Minoxidil eligibility and contraindications

Minoxidil is a topical treatment that stimulates hair growth by improving blood flow to hair follicles. It can be used by both men and women. The doctor will look for:

  • Heart Conditions: Individuals with certain heart conditions (e.g., angina, heart failure) should use Minoxidil with caution, as it can affect blood pressure and heart rate.
  • Scalp Health: Severe scalp irritation, inflammation, or open wounds can make Minoxidil unsuitable.
  • Allergies: A known allergy to Minoxidil is a contraindication.

The doctor's review ensures your safety and the effectiveness of the treatment.

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

Hair loss treatments like Finasteride and Minoxidil are designed to combat androgenetic alopecia (male and female pattern baldness). They work through different mechanisms:

  • Finasteride: This oral medication inhibits the enzyme 5-alpha-reductase, reducing the conversion of testosterone to DHT. High levels of DHT shrink hair follicles, leading to thinning and loss. By lowering DHT, Finasteride can slow hair loss and promote regrowth. Realistic timelines for results are typically 3-6 months to see initial changes, with full effects taking 12 months or more. It does not cure baldness, and continued use is necessary to maintain results.
  • Minoxidil: This topical solution widens blood vessels in the scalp, increasing blood flow and nutrient delivery to hair follicles. This stimulates dormant follicles and prolongs the growth phase of existing hairs. Results usually appear after 2-4 months of consistent use, with maximum benefits around 12 months. Like Finasteride, it requires continuous application to sustain effects.

Neither medication offers a 'quick fix' or guarantees a full head of hair. They are most effective at slowing progression and promoting regrowth in areas of thinning, rather than restoring completely bald areas. Consistency and patience are key.

Side effects and when to stop

Like all medications, Finasteride and Minoxidil can have side effects. It's important to be aware of these and to consult your Hi-Doctor physician if you experience any concerning symptoms.

Finasteride side effects:

  • Sexual Dysfunction: Decreased libido, erectile dysfunction, and ejaculation disorders are reported in a small percentage of users.
  • Mood Changes: Some individuals may experience anxiety or depressive symptoms.
  • Breast Tenderness/Enlargement: Rarely, gynecomastia (breast growth) can occur.

If you experience persistent or severe side effects, especially sexual dysfunction or mood changes, discuss this with your doctor. They may recommend adjusting the dosage or discontinuing the treatment.

Minoxidil side effects:

  • Scalp Irritation: Redness, itching, dryness, or flaking of the scalp are common, especially when first starting treatment.
  • Unwanted Hair Growth: In some cases, Minoxidil can cause hair growth on other parts of the body, such as the face.
  • Dizziness or Lightheadedness: This is rare but can occur due to its vasodilating effects.
  • Rapid Heartbeat/Palpitations: Very rare, but if experienced, stop use and seek medical advice.

If scalp irritation is severe or if you notice systemic effects like dizziness or palpitations, discontinue use and consult your doctor.
