In short: in trials they work about equally well. The choice usually comes down to convenience and side effects. Topical minoxidil mostly stays on the scalp. Oral minoxidil is easier to use, but it acts on the whole body, so it needs a prescription and monitoring.
Side by side

| Effects on the whole body | Rare | Possible; needs monitoring |
| Hair styling and oiling | Can make hair greasy; timing with oiling matters | No effect on hair texture or routine |
| Who it suits | Most people starting out | People with scalp irritation, poor adherence, or poor response to topical |
| Cost per month | ₹160–300 generic | Tablets are cheap (about ₹20–420 per strip of 10, depending on brand and strength); doctor visits add cost |
How to choose
Start with topical if:
- you're new to treatment,
- you have heart or blood pressure conditions,
- you want to avoid effects on the whole body.
Ask your doctor about oral if:
- topical minoxidil irritates your scalp (even the foam),
- you keep missing applications,
- you've used topical consistently for 6–12 months with little response,
- you're a woman with thinning, and facial hair isn't a major concern (low doses are used).
Not for oral without specialist advice: heart disease, low blood pressure, pregnancy, breastfeeding.
Oral minoxidil vs finasteride
They're different medicines that do different jobs. Oral minoxidil stimulates growth; finasteride lowers DHT (men only). Many men use both. → Minoxidil vs finasteride
FAQs
Can I use oral and topical together? Sometimes, under a dermatologist. Don't combine them on your own.
Is oral minoxidil "stronger"? Not in the trials so far. It's more convenient and reaches every follicle, but it doesn't clearly grow more hair than topical 5%.
See a doctor soon if you have: round bald patches that appear suddenly · hair coming out in clumps · redness, pain, pus, scaling or scarring on the scalp · hair loss with fever, weight loss, irregular periods, acne or new facial hair · eyebrow or eyelash loss · hair loss in a child.
