The most common mistake people make with hair loss: they start with a treatment instead of a starting point. They buy whatever shampoo has the best packaging, or they fall down a Reddit thread, or they order a supplement stack with zero idea whether they are dealing with early thinning or advanced crown loss. The remedy either does nothing or addresses the wrong stage entirely. Starting with a clear picture of what is actually happening saves real money and real time.
Start Here: Know What You Are Working With
1. HairLine AI (Free Browser Tool)
Cost: $0. No account. No credit card.
This is a browser-based tool that reads a webcam shot or uploaded photo and uses Google’s Gemini 3 Pro vision model to classify your Norwood stage, the same staging system clinicians use. It also outputs a rough graft count and estimated transplant cost range, all inside a single results screen. The facial geometry reading is handled by MediaPipe, the open-source tracking library from Google.
Why put it first? Because it gives you an objective reference point before you spend anything. Most product quizzes are designed to sell you the quiz-maker’s product. This tool has no product to sell. It tells you your stage, points you toward what treatment tier makes sense (topical, oral, surgical), and flags when a real consultation would be appropriate. The output is a guide, not a clinical diagnosis, but it is a better-informed guess than most people start with.
For Scalp Health and Early-Stage Thinning
2. Ketoconazole Shampoo (OTC, ~$10 to $20)
Nizoral 1% sits on drugstore shelves. The theory is that it reduces scalp DHT-linked inflammation, which is one factor in androgenetic hair loss. The evidence is modest but real. Use it two or three times per week, not daily, since it can dry the scalp out. It is not a standalone fix, but it costs almost nothing to add.
3. Derma-Rolling (Microneedling at Home, ~$15 to $40)
A 0.5 mm to 1.0 mm derma roller used weekly on the scalp is thought to stimulate growth factors and, importantly, may improve minoxidil absorption when the two are paired. A 2013 study in the *Journal of Trichology* compared minoxidil alone to minoxidil plus microneedling; the combination group outperformed. Results are not overnight. Sterilize your roller every single time.

4. Keranique (Women’s OTC Line)
Keranique builds its line around 2% minoxidil formatted specifically for women, paired with thickening shampoos and conditioners. The active ingredient is the same thing in generic women’s minoxidil, but the full regimen is marketed to women who want a single-brand system rather than mixing products. Widely available at major retailers.
The Evidence-Backed Mainstays
5. Generic Minoxidil (Topical, OTC, ~$10 to $25 for a 3-month supply)
Minoxidil has decades of clinical data behind it. It works by prolonging the anagen growth phase and is the only topical ingredient with real FDA backing for hair regrowth. It does not stop DHT. It works best at earlier Norwood stages and must be continued indefinitely. Stopping means losing whatever you gained, typically within a few months.
6. Oral Minoxidil (Low-Dose, Rx in the US, ~$20 to $50/month)
The oral version, taken at doses far lower than the blood pressure indication (0.625 mg to 2.5 mg daily), has grown dramatically in clinical popularity since around 2020. It skips the scalp application entirely. Side effects like fluid retention and body hair growth are possible. Requires a prescription and a clinician who is comfortable with off-label prescribing.
7. Finasteride (Generic, Rx, ~$10 to $30/month)
Finasteride blocks the conversion of testosterone to DHT. It is the most-studied oral treatment for male pattern hair loss and genuinely effective for maintaining and sometimes recovering hair in men. A minority of users report sexual side effects; those typically resolve after stopping the medication, though there are ongoing discussions in the literature about post-finasteride syndrome. Not approved for women who may become pregnant. Never take it without a doctor’s guidance.
Managed OTC and Telehealth Options
8. Hims (Topical Finasteride + Various Combos)
Hims is the only major telehealth platform currently offering topical finasteride, which combines the DHT-blocking mechanism with lower systemic absorption than the oral pill. They also carry oral finasteride, topical and oral minoxidil, and compound combination products. Pricing varies by formula and plan length.
9. Keeps (Budget-Friendly Telehealth)
Keeps focuses specifically on hair loss rather than general wellness. Their 3-month plan pricing tends to undercut single-month pricing noticeably, and shipping runs around $5. They offer finasteride and minoxidil, though their formula variety is narrower than some competitors.
10. Happy Head (Custom Prescription Compounds)
Happy Head writes prescriptions for custom topical formulas that can combine finasteride, minoxidil, and other ingredients in a single compound. The personalization angle appeals to people who have already tried single-ingredient products without enough response.
Supplements Worth Knowing About
11. Saw Palmetto, Biotin, and Nutrafol-Style Stacks (~$20 to $80/month)
Saw palmetto is the supplement most often discussed as a mild natural DHT inhibitor, though the clinical evidence is far thinner than for finasteride. Biotin deficiency can cause hair shedding, but supplementing beyond normal levels does not produce extra growth in people who are not deficient. Multi-ingredient stacks like Nutrafol add adaptogens and anti-inflammatory botanicals. Some users report real improvement; the controlled trial data is limited. These are reasonable additions to a broader regimen, not replacements for proven treatments.
A Quick Note on Expectations
No remedy on this list works in two weeks. Minoxidil and finasteride results take 3 to 6 months minimum, and the scientific literature consistently shows that most of those results disappear when treatment stops. Supplements show even slower and less predictable timelines. Starting with a realistic picture of your current stage, whether through a tool like HairLine AI or a dermatologist visit, makes every dollar spent after that more likely to land in the right place.
Common Questions
Does using HairLine AI replace seeing a dermatologist about hair loss?
No, and the tool itself flags this. HairLine AI gives you a Norwood stage estimate and a rough cost range based on a photo, which is genuinely useful for orienting yourself before spending money on products. A dermatologist can rule out medical causes, check bloodwork, and prescribe treatments. Use the tool to show up to that appointment better prepared.
Can women use the same finasteride and minoxidil products listed here, or are the doses different?
Minoxidil at 2% is FDA-approved for women; the 5% concentration is used off-label under medical supervision. Finasteride is not approved for women who may become pregnant due to serious fetal risk. Keranique and other women-specific lines default to 2% minoxidil precisely because of these distinctions. Women should confirm dosing with a prescriber before starting any of these.
Is there a meaningful difference between Keeps and Hims for someone who just wants basic finasteride and minoxidil?
The core medications are the same generics either way. Hims currently offers topical finasteride, which Keeps does not, so the choice matters if you want lower systemic absorption from finasteride. For straight oral finasteride plus topical minoxidil, the main variables are pricing structure, shipping cost, and how each platform handles follow-up consultations.
How long should someone use a derma roller alongside minoxidil before deciding whether it is working?
The 2013 Dhurat study ran for 12 weeks before measuring results, and that is a reasonable minimum checkpoint. Most hair cycling research suggests 6 months gives a clearer picture. Consistency matters more than frequency. Weekly sessions with a properly sterilized 0.5 mm to 1.0 mm roller, combined with minoxidil applied afterward, is the protocol closest to what the published data actually tested.
Are Nutrafol-style supplement stacks worth the price compared to cheaper saw palmetto capsules?
Standalone saw palmetto capsules run $10 to $20 a month and contain the ingredient with the most-discussed natural DHT-inhibiting mechanism. Nutrafol-style stacks cost $80 or more and add adaptogens, marine collagen, and botanical blends. The added ingredients have thin independent trial data for hair specifically. If budget is a concern, a low-cost saw palmetto supplement paired with a proven topical is a more defensible starting point.
