Who qualifies for minoxidil or finasteride

The decision to prescribe minoxidil or finasteride for hair loss after bariatric surgery rests with our EU-licensed doctors. They carefully assess your medical history, current health, and the specifics of your hair loss. Generally, doctors look for patients who:

• Are experiencing telogen effluvium related to bariatric surgery.
• Have no contraindications to minoxidil (e.g., certain heart conditions) or finasteride (e.g., pregnancy, liver issues for women).
• Are willing to commit to consistent treatment, as results take time.
• Are men for finasteride prescriptions, as it is generally not recommended for women, especially those of childbearing potential.

Your doctor will determine if these treatments are appropriate and safe for your individual case.

What minoxidil and finasteride actually do (and don't do)

Minoxidil is a topical solution that works by widening blood vessels and opening potassium channels, which allows more oxygen, blood, and nutrients to reach the hair follicles. This can help stimulate hair growth and increase the size of existing follicles. It's effective for various types of hair loss, including the telogen effluvium often seen after bariatric surgery. You typically apply it directly to the scalp once or twice daily. Results usually appear after 2-4 months of consistent use.

Finasteride is an oral medication primarily used for male pattern baldness. It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is a hormone that can shrink hair follicles in genetically susceptible individuals. By reducing DHT levels, finasteride can slow down hair loss and promote regrowth. It is generally not prescribed for women due to potential side effects and risks, particularly during pregnancy. Results for finasteride can take 3-6 months to become noticeable.

Neither medication offers an instant cure; consistency is key. They aim to promote regrowth and prevent further loss, but individual results vary. They do not address underlying nutritional deficiencies, which should be managed in parallel.

Side effects and when to stop

Like all medications, minoxidil and finasteride can have side effects. It's crucial to be aware of these and to consult your doctor if they occur.

Minoxidil common side effects include scalp irritation, itching, dryness, or flaking. Less common but more serious side effects can include unwanted facial hair growth, dizziness, rapid heartbeat, or swelling of hands and feet. If you experience any severe side effects, stop using minoxidil and seek medical advice immediately.

Finasteride in men can sometimes cause sexual side effects like decreased libido, erectile dysfunction, or ejaculation disorders. These side effects are often reversible upon stopping the medication. Other side effects can include breast tenderness or enlargement. If you experience persistent or concerning side effects, contact your doctor. Women of childbearing potential should not handle crushed or broken finasteride tablets due to the risk of birth defects.

Always discuss any concerns or side effects with your Hi-Doctor.ai doctor. They will advise you on whether to continue, adjust, or stop your treatment.
