Hair Restoration — A Practical Guide to What Actually Works for Men

Androgenic alopecia is genetic susceptibility to dihydrotestosterone (DHT), a more potent androgen than testosterone. DHT binds to receptors on scalp follicles in genetically primed areas (frontal hairline, crown) and progressively miniaturizes them. The genetics involve multiple genes across both parents — not just maternal as old folklore suggests. Once miniaturization is advanced, follicles eventually stop producing visible hair. Earlier intervention preserves more.

Finasteride blocks Type II 5-alpha reductase (the enzyme converting testosterone to DHT) and is FDA-approved for hair loss at 1mg daily. Dutasteride blocks both Type I and Type II, suppressing DHT more completely — typically ~90% vs ~70% with finasteride. Dutasteride is FDA-approved for BPH, used off-label for hair at 0.5mg daily. Some men who plateau on finasteride do better on dutasteride; side-effect risk profile is similar but dose-dependent. The right choice depends on response, side-effect tolerance, and prescriber comfort with off-label use.

Yes, minoxidil works — particularly in the crown — by extending the anagen (growth) phase of the hair cycle. Topical (Rogaine) is FDA-approved and widely available; oral minoxidil (low dose, 1.25–5mg) is used off-label with growing evidence and stronger scalp penetration. Topical works well but requires daily compliance; oral is more convenient but can cause ankle swelling and unwanted body hair. Either takes 4–6 months for visible results. Stopping reverses gains within 3–6 months.

FUE (follicular unit extraction) typically runs $4,000–$15,000+ depending on graft count and surgeon. FUT (follicular unit transplantation, strip method) is slightly less. Premium surgeons with high-volume reputations charge significantly more — $20,000–$40,000 for large sessions is not uncommon at top US clinics. Medical tourism (Turkey, Mexico) offers lower prices with mixed quality. Cost-per-graft is the standard comparison metric, but surgeon skill and aftercare matter more than per-graft pricing.

Transplanted follicles are permanent — they retain donor-area DHT resistance. But your native non-transplanted hair continues to thin per your genetic pattern. Without ongoing medication (finasteride or dutasteride), most transplant patients see continued recession or thinning around the transplant zone, sometimes requiring a second procedure 5–10 years later. Medication preserves what you have; transplant restores what you lost. The combination is the durable strategy.
