Let's be direct: no treatment cures baldness. What the best treatments do is slow or stop the underlying process — and in some cases partially reverse it. Here's the full landscape, sorted by strength of evidence, with honest assessments of what each option can and can't do.
Treatments With Strong Clinical Evidence
Finasteride (Prescription)
Finasteride inhibits Type 2 5-alpha-reductase, reducing scalp DHT by approximately 60%. It's the most extensively studied hair loss treatment, with Phase III trials showing 83% of users maintained or increased hair count over 2 years.
What it does well: Halts progression in most men. Produces measurable regrowth in many, particularly at the crown and vertex.
What it doesn't do: It's not a cure — hair loss resumes if you stop. Works better for crown than hairline. Sexual side effects (reduced libido, erectile dysfunction) affect 1–2% of users in clinical trials, with some reports of persistent effects.
Available as: Oral tablets (Propecia/generic), or topical formulations that reduce systemic exposure — such as Procerin Rx, which combines topical finasteride with minoxidil.
Minoxidil (OTC)
The most widely used over-the-counter treatment. Originally a blood pressure drug, minoxidil extends the hair growth phase and improves follicular blood supply. FDA-approved for hair loss since 1988.
What it does well: Proven efficacy for crown/vertex thinning. ~60% of men see measurable improvement. Available without prescription.
What it doesn't do: Doesn't address DHT — treats the symptom, not the cause. Hair regrown with minoxidil is lost within months of stopping. Less effective for hairline recession. Can cause scalp irritation.
Hair Transplant Surgery
FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplantation) relocate DHT-resistant follicles from the back of the scalp to balding areas. Results are permanent for transplanted hairs.
What it does well: Only option that permanently restores hair in bald areas. Natural-looking results with modern techniques.
What it doesn't do: Doesn't stop ongoing loss in non-transplanted follicles — most surgeons recommend continuing DHT-blocking treatment post-surgery. Expensive ($4,000–$15,000+). Limited by donor hair supply. Not appropriate for early-stage loss.
Treatments With Moderate Evidence
Natural DHT Blockers (OTC Supplements)
Saw palmetto, beta-sitosterol, pumpkin seed oil, and other natural compounds that inhibit 5-alpha-reductase at lower potency than finasteride. Available without prescription.
What the evidence shows: Several ingredients have small-to-moderate trial support. Saw palmetto showed statistically significant improvement in a head-to-head comparison with finasteride — though finasteride was more effective (66% vs. 38% improvement). Pumpkin seed oil showed 40% increase in hair count vs. placebo in a well-designed 2014 RCT.
Combination products that pair multiple DHT-blocking compounds with a topical component — such as Procerin — have shown results in IRB-approved studies. The combination approach (oral + topical) addresses DHT from both systemic and local pathways.
What they don't do: Natural DHT blockers don't match pharmaceutical-grade DHT suppression. They work best for early-stage loss and as a maintenance approach. Not a substitute for prescription treatment in advanced cases.
PRP (Platelet-Rich Plasma)
Concentrated platelets from your own blood are injected into the scalp. The growth factors are thought to stimulate follicle activity.
What the evidence shows: Several small studies show modest improvement in hair density. Evidence is growing but not yet definitive. Expensive ($500–$2,000 per session, multiple sessions needed). No standardized protocol — results vary significantly between practitioners.
Treatments That Don't Work (Despite Their Marketing)
This is where most of the hair loss industry's revenue comes from:
- Biotin supplements — Unless you have a documented biotin deficiency (rare), supplementation does nothing for androgenetic alopecia. The most overhyped ingredient in the hair loss space.
- Shampoos marketed as 'hair loss treatments' — The contact time of a shampoo on your scalp is measured in seconds. No active ingredient is meaningfully absorbed. Ketoconazole shampoo is the one exception — it has mild anti-androgenic properties when used regularly as an adjunct.
- Essential oils and scalp massages — No clinical evidence supports these for androgenetic alopecia. Some small studies on rosemary oil exist, but methodology is weak.
- Laser caps and combs — FDA-cleared (a low bar — it means 'probably safe,' not 'proven effective'). Evidence is limited and inconsistent. Expensive for uncertain benefit.
- Any product calling itself a 'cure' — If a product claims to cure baldness, it's either making an illegal health claim or it's not talking about androgenetic alopecia. Be skeptical.
The Realistic Approach
The most effective strategy for most men combines:
- A DHT-blocking component — pharmaceutical or natural, depending on your risk tolerance and stage of loss
- A growth-stimulating component — minoxidil or a topical activator
- Consistent, long-term use — months to see results, years to maintain them
- Realistic expectations — you're managing a condition, not curing a disease
Starting early matters more than which specific product you choose. A man who starts a basic DHT blocker at Norwood II will likely keep more hair than one who starts the most aggressive treatment at Norwood V.
