The single thing that matters most here is knowing where you stand before you spend a dollar. Treatment choice without staging is guesswork.
This guide lays out the real decision criteria first, then maps the most useful tools and services onto each one.
How to Decide: The Criteria That Matter
Before picking a product, ask yourself five questions:
- What stage am I at? Early diffuse thinning responds differently than a receding hairline at Norwood 4.
- Do I want to address DHT (the root cause) or just stimulate growth? Finasteride blocks DHT. Minoxidil widens blood vessels. Different mechanisms.
- Am I comfortable with an Rx and its side-effect profile? Finasteride requires a prescription and carries a documented minority risk of sexual side effects.
- How long can I commit? Both drugs require ongoing use. Stopping reverses gains.
- Am I a candidate for transplant instead, or as well? That changes the whole calculus.
Now, the ten things worth knowing.
1. HairLine AI: Free Norwood Staging Before You Spend Anything
Cost: $0. No account. No credit card.
You open the browser tool, upload a photo or use your webcam, and get back a Norwood stage classification, an estimated graft count, and a rough transplant cost range. The system runs Google’s Gemini 3 Pro vision model against detected facial geometry to place you on the scale. It is an information-first starting point, not a pharmacy or clinic. The value is simple: you go into any consultation or product page already knowing your stage, not relying on a brand’s quiz to tell you what to buy. Honest caveat built in: the AI read is a guide, not a clinical diagnosis.
2. Finasteride Targets the Cause, Minoxidil Does Not
Finasteride is a 5-alpha-reductase inhibitor. It reduces dihydrotestosterone, the hormone that miniaturizes follicles in androgenetic alopecia. Minoxidil does not touch DHT. It improves scalp blood flow and extends the growth phase. Two different problems addressed. That is why many clinicians recommend combining them.
3. Finasteride Requires a Prescription. Minoxidil Does Not.
Minoxidil 2% and 5% are over the counter. Generic bottles run $10 to $20 a month. Finasteride needs a licensed prescriber, which is why telehealth platforms exist in this space.
4. Hims Offers the Widest Topical Menu
Hims is the only major telehealth brand currently offering topical finasteride as a standalone option, alongside oral finasteride, topical and oral minoxidil, and combination formulas. Useful if you want to avoid systemic finasteride exposure while still getting DHT suppression at the scalp.
5. Keeps Is Worth Checking If Budget Is the Priority
Keeps structures its pricing around three-month supply plans, which brings per-month cost down. Shipping runs about $5. The product range covers finasteride and minoxidil, nothing exotic, but the basics at a lower recurring spend than some competitors.
6. Roman Sticks to Oral Generics and Solution Minoxidil
Roman (now Ro) does not carry minoxidil foam. If you prefer foam application, check the product page carefully before subscribing. Straightforward generic oral finasteride is available through a telehealth consult.
7. Happy Head Focuses on Compounded Topicals
Happy Head prescribes custom-compounded topical formulas that can combine finasteride and minoxidil in a single application. Compounding is not FDA-approved as a drug category, but individual ingredients are well-studied. Worth discussing with a dermatologist first.
8. Results Take Months. Both of Them.
Three to six months is the minimum window before most people see meaningful change. Neither drug works fast. Photos taken at the same lighting and angle, one month apart, are the only reliable way to track progress.
9. Stopping Either Drug Reverses the Benefit
This is not a fine-print caveat. It is the central fact of both treatments. Whatever hair you keep on finasteride, you lose again roughly 6 to 12 months after stopping.
10. A Dermatologist Call Costs Less Than a Year of the Wrong Product
Before committing to any subscription, a single telehealth dermatology visit typically runs $50 to $100 and can rule out non-androgenetic causes entirely.
Common Questions
Does your Norwood stage actually change which drug a doctor will recommend?
Yes, it often does. Clinicians tend to prioritize finasteride for earlier stages where DHT suppression can slow or halt progression, while minoxidil gets added for its growth-stimulating effect. At later stages like Norwood 5 or 6, the conversation often shifts toward whether medication alone is realistic or whether transplant consultation makes more sense.
If Hims offers topical finasteride, does that mean you skip the side-effect risk entirely?
Not entirely. Topical finasteride does produce lower systemic DHT reduction than the oral pill, which is why some men prefer it. But some absorption still occurs, and the long-term side-effect data on topical formulations is thinner than the decades of evidence behind oral finasteride. It is a different risk profile, not a zero-risk one.
Can a free AI staging tool like HairLine AI actually replace the intake quiz on platforms like Keeps or Hims?
It replaces the part where a brand quiz nudges you toward its own products. HairLine AI gives you an independent Norwood read before you visit any telehealth site, so you arrive with context rather than letting the platform define your starting point. It does not replace the licensed clinician review those platforms provide before prescribing.
Why does Happy Head use compounded formulas instead of standard generics, and does that matter?
Compounding lets a pharmacy combine finasteride and minoxidil into one topical, which some users find easier to apply consistently. The tradeoff is that compounded products go through less regulatory oversight than FDA-approved generics. The active ingredients are well-studied individually, but the specific compounded formulation itself has not gone through the same approval process.
If you stop minoxidil after two years of use, do you lose more hair than you would have without it?
You return roughly to where you would have been without treatment, not to a worse baseline. The common fear that stopping causes accelerated loss beyond your natural trajectory is not supported by the published evidence. You do shed the hair that minoxidil was maintaining, which can feel dramatic, but it reflects the underlying loss that was already happening.
A Note on This Guide
Nothing here is medical advice. Finasteride side effects are real for a minority of users, and anyone considering it should talk to a licensed clinician first. AI staging tools give you a useful starting framework. They do not replace a trained eye or blood work.
