Most hair loss products are noise. A short list of treatments actually has clinical evidence behind it, and knowing which ones they are saves you from wasting months on supplements that do nothing measurable.
Here is a ranked comparison of the seven options with the strongest track records, followed by honest detail on each.
Comparison at a Glance
| Treatment | Rx Required | Monthly Cost (approx.) | Works For | Time to See Results | Keep Using Forever? |
| Oral Finasteride | Yes | $15 to $30 | Men (AGA) | 3 to 6 months | Yes |
| Topical Minoxidil | No (OTC) | $10 to $25 | Men and Women | 4 to 6 months | Yes |
| Oral Minoxidil (low-dose) | Yes | $20 to $40 | Men and Women | 3 to 6 months | Yes |
| Topical Finasteride | Yes | $40 to $75 | Men | 3 to 6 months | Yes |
| Ketoconazole Shampoo | No | $10 to $20 | Men and Women | Ongoing | Yes |
| Derma Rolling (microneedling) | No | $20 to $50 (device, one-time) | Men and Women | 4 to 8 months | Ongoing sessions |
| Hair Transplant Surgery | N/A | $4,000 to $15,000+ (one-time) | Men and Women | 9 to 18 months | No (but meds often recommended post-op) |
1. Oral Finasteride: The Benchmark for Male Pattern Loss
Nothing has a longer evidence record in androgenetic alopecia than oral finasteride. The 1 mg daily dose reduces scalp DHT by roughly 60 to 70 percent. That number comes from the original clinical trials, not marketing copy.
Keeps and Hims both supply it as a generic for under $30 a month, often cheaper on three-month plans. Keeps specifically targets hair loss as its main focus, which keeps the intake process direct. Roman (now Ro) also offers a generic oral version.
One real caveat: a minority of men report sexual side effects including reduced libido or erectile changes. These resolve in most cases after stopping, but they are real and documented. Anyone starting finasteride should discuss this with a clinician first. The drug is not appropriate for women who could become pregnant.
Results take time. Expect three to six months before noticing density changes, and you stop the drug, you lose whatever you gained within about a year.
2. Topical Minoxidil: Proven, Over-the-Counter, and Genuinely Effective
Minoxidil works. It prolongs the anagen (growth) phase and widens hair follicles. Generic versions cost around $10 a month. The name-brand Rogaine charges more for the same active ingredient.
The foam form (5%) tends to cause less scalp irritation and is easier to apply than the liquid. Women should use the 2% concentration or confirm with a doctor before going to 5%. Keranique markets an OTC minoxidil product specifically positioned for women, though generic 2% minoxidil does the same job at lower cost.
Stop applying it and hair shed returns within a few months. That is not a flaw in the product. It is just how the mechanism works.
3. Low-Dose Oral Minoxidil: A Newer Option Getting Serious Attention
Dermatologists have been prescribing oral minoxidil off-label at 0.25 mg to 2.5 mg daily for several years now, and the clinical data coming out of this period is encouraging. It sidesteps scalp application entirely.
Hims now offers oral minoxidil as part of its lineup, and Happy Head builds it into some of its custom compound prescriptions. Side effects at low doses are usually mild, mostly unwanted facial hair in some women and minor fluid retention. Blood pressure changes are possible but rare at these doses.
It requires a prescription. See a dermatologist or a licensed telehealth clinician before starting.
4. Topical Finasteride: Reduced Systemic Exposure, Similar Local Effect
Topical finasteride delivers the DHT-blocking effect at the scalp while keeping blood serum levels lower than the oral version. The theory is fewer systemic side effects. The early data supports this, though long-term head-to-head studies are still accumulating.
Hims is currently the only major direct-to-consumer brand offering topical finasteride as a standalone option. Happy Head also formulates custom topical prescriptions that can combine finasteride and minoxidil in one solution. BosleyRx, which carries the transplant-focused Bosley brand’s clinical history, also moves into this space through its Rx program.
Cost runs higher than oral finasteride, typically $40 to $75 a month depending on the formulation.
5. Ketoconazole Shampoo: Not a Miracle, But a Legitimate Adjunct
Ketoconazole is an antifungal. At 1% to 2% concentration, it also has a mild anti-androgenic effect at the scalp. Studies comparing it to minoxidil in regrowth are modest and mixed, but consistent use two to three times a week appears to support scalp health and may slow shedding.
It costs almost nothing. Nizoral 1% is widely available OTC. The 2% version requires a prescription in some markets. If you are already on finasteride or minoxidil, adding ketoconazole shampoo is low risk and low cost.
Do not expect it to do heavy lifting on its own.
6. Derma Rolling (Microneedling at Home): Underrated When Done Correctly
A 0.5 mm to 1.5 mm derma roller used on the scalp once weekly creates micro-injuries that stimulate growth factors. Multiple small randomized controlled trials have shown that combining derma rolling with minoxidil outperforms minoxidil alone.
Technique and hygiene matter. A dirty roller can cause folliculitis. Replace the device every three to four months. Rollers with 0.5 mm needles run $20 to $40. This is one of the few evidence-supported additions to a standard regimen that costs almost nothing ongoing.
If you want to understand your baseline thinning pattern before committing to any regimen, tools like HairLine AI let you upload a photo and get an AI-generated Norwood stage read for free, which at least gives you a starting reference point before your first dermatologist appointment.
7. Hair Transplant Surgery: Permanent Redistribution, Not a Cure
A transplant moves DHT-resistant follicles from the back of the scalp to thinning areas. Done well, it is permanent. Done poorly or too early, it can leave patchy results that are hard to correct.
FUE (follicular unit extraction) is now the standard technique. Costs run from $4,000 for limited work to well above $15,000 for larger sessions. HairClub and Bosley both operate clinic networks across the US for in-person consultations. Neither cheap nor quick, hair growth from transplanted follicles takes nine to eighteen months to mature.
Most surgeons recommend continuing finasteride or minoxidil after surgery to protect non-transplanted hair. A transplant addresses existing loss. It does not stop future loss in untreated areas.
A Word Before You Buy Anything
Nothing here replaces a conversation with a licensed dermatologist or physician. Side effects are real, individual responses vary considerably, and some conditions that look like androgenetic alopecia are something else entirely. An online photo analysis or a telehealth quiz is a starting point, not a clinical assessment. The treatments above have evidence behind them, but results still differ from person to person, and every one of the ongoing treatments requires sustained use to maintain any benefit.
Common Questions
If Keeps and Hims both offer generic finasteride, is there any real difference between them?
The active ingredient is identical. Both deliver 1 mg oral finasteride. Keeps focuses exclusively on hair loss, so the intake questionnaire and follow-up messaging stay on topic. Hims covers a wider range of men’s health products. Pricing is comparable, though promotional rates change often enough that checking both directly is worth a few minutes.
Can a woman use any of the treatments on this list safely?
Topical minoxidil at 2% is the clearest yes. Low-dose oral minoxidil is also prescribed to women, with a doctor’s supervision. Finasteride in any form is not recommended for women who are pregnant or could become pregnant, due to documented risks to a male fetus. Ketoconazole shampoo and derma rolling carry no specific contraindication for women.
Does adding a derma roller actually change outcomes, or is that overstated?
The Dhurat 2013 trial found measurably better hair counts when microneedling was combined with minoxidil versus minoxidil alone. The effect is real but not dramatic on its own. The low cost makes it a sensible add-on rather than a standalone strategy. Hygiene is the main variable people underestimate, a contaminated roller does more harm than good.
Happy Head offers compounded topical prescriptions. What does compounding actually mean here?
A compounding pharmacy mixes ingredients to a specific formula rather than dispensing a mass-manufactured product. Happy Head uses this to combine finasteride and minoxidil in a single topical solution at custom concentrations. It is legal and common in dermatology, though compounded products are not FDA-approved as finished drugs, meaning the individual ingredients are approved but the specific formulation is not reviewed the same way.
At what point does it make more sense to consult Bosley or HairClub about a transplant rather than continuing medication?
Generally, surgeons want to see that loss has stabilized before operating, because transplanting into an actively thinning scalp can produce uneven results over time. If you have been on finasteride or minoxidil for at least a year with minimal further loss, and the thinning area is well-defined, a consultation becomes worthwhile. Both Bosley and HairClub offer in-person assessments, which is a more reliable starting point than an online quiz.
