Finasteride & Minoxidil
Complete Medical Hair Loss Guide.
Finasteride and Minoxidil are the two most clinically proven medical treatments for androgenetic alopecia. This guide explains how they work, when to use them and how they fit alongside a hair transplant.

The Two Main Options
Finasteride vs Minoxidil —
Full Comparison
| Factor | Finasteride (Propecia) | Minoxidil (Rogaine) |
|---|---|---|
| How it works | Blocks 5-alpha reductase — reduces DHT by ~70% | Widens blood vessels, extends anagen growth phase |
| Form | Daily oral tablet (1mg) or topical | Topical foam/solution (5%) or oral |
| Best for | Stopping / slowing recession — front + top | Crown and vertex density |
| Effectiveness | Stops loss in 90% of men | Partial regrowth — 60% of users |
| Time to results | 3–6 months to see stabilisation | 4–6 months to see density change |
| Side effects | Possible in 2–3% (libido, mood) | Scalp irritation, initial shedding |
| If stopped? | Loss resumes within 6–12 months | Gains lost within 3–6 months |
| Available to women? | No — not recommended | Yes — FDA approved for women |
| Combined use? | Both together: most effective medical protocol | |
Both drugs are FDA-approved and act on completely different mechanisms — which is why Dr. Arslan recommends combining them rather than choosing between them.
- Finasteride is a Type II 5-alpha-reductase inhibitor — it blocks the enzyme that converts testosterone into DHT, the hormone responsible for miniaturising follicles at the hairline and crown
- Minoxidil does not touch hormones. It is a vasodilator that improves blood flow and oxygen delivery to the follicle and extends the anagen (growth) phase of the hair cycle
- Because the two drugs act on separate pathways, using them together addresses hair loss from two directions at once — this is why the combined protocol consistently outperforms either drug used alone
- Neither drug restores follicles that have already gone permanently dormant — that is the point at which a transplant becomes the only remaining option
When to Use Medical Treatment
Medical First, Surgery
When Needed
Dr. Arslan recommends medical treatment at every stage — not as an alternative to surgery, but as a lifelong strategy to protect remaining native hair both before and after any transplant procedure.
- Norwood I–II: Finasteride + Minoxidil — may avoid or delay surgery
- Norwood III+: Continue medical therapy post-transplant to protect native hair
- All stages: Medical treatment slows future loss progression
- Post-transplant: Finasteride recommended indefinitely
- Women: Minoxidil is the primary medical option — Finasteride not recommended
Consistency matters more than which drug you start with. Missed doses reduce effectiveness, and stopping — even briefly — allows DHT levels to rebound and hair loss to resume. Dr. Arslan reviews your Norwood stage, donor density and family history before recommending a regimen, then reassesses progress at follow-up consultations rather than leaving patients on a fixed prescription indefinitely.
Dr. Arslan on Medical Therapy
"A hair transplant restores what you have lost. Finasteride protects what you still have. Without it, you may transplant today and continue losing tomorrow. I recommend it to every patient unless there is a medical reason not to."

Before You Start
Who Is a Good Candidate
for Medical Treatment?
Good Candidates
- Norwood I–III hair loss — visible thinning or recession, but no fully bald areas yet
- Early diffuse thinning in women (Ludwig I–II)
- Family history of androgenetic alopecia — started preventively before visible loss progresses
- Patients preparing for or recovering from a hair transplant, to protect the native hair surrounding the transplanted area
- Anyone able to commit to daily, long-term use — both drugs only work for as long as you keep taking them
Consider Alternatives First
- Norwood VI–VII with large, fully bald areas — dormant follicles will not respond to medication, and a transplant is the only way to restore density there
- Women of childbearing age or planning pregnancy — Finasteride carries a teratogenicity risk; Minoxidil or Spironolactone are the safer options
- Anyone expecting a fast, one-time fix — Finasteride and Minoxidil are gradual maintenance treatments, not a single procedure
- Anyone with unexplained scalp irritation, broken skin or a known hypersensitivity to either drug — a physician consultation is required before starting

Ask Dr. ArslanCan Finasteride reverse hair loss?+
Finasteride stops or significantly slows progression in approximately 90% of men. It can sometimes cause partial regrowth of miniaturised hair. However, it cannot restore hair from permanently dormant follicles — only a transplant does that.
Are Finasteride side effects common?+
Sexual side effects (libido changes, erectile function) occur in approximately 2–3% of men taking Finasteride. Post-Finasteride syndrome is rare and controversial. Side effects typically resolve on stopping the medication. Always discuss risks and benefits with Dr. Arslan.
Does Minoxidil work for women?+
Yes — Minoxidil (5% topical or oral) is FDA-approved for female androgenetic alopecia. Finasteride is not recommended for women of childbearing age due to teratogenicity risk. Spironolactone (anti-androgen) is sometimes prescribed for women instead.
Do I need to take Finasteride forever?+
Yes — benefits stop within 6–12 months of discontinuing. Most patients consider this a lifelong strategy after seeing the results. The cost of daily tablets is modest compared to the cost of transplanting hair that could have been protected.
Should I stop Finasteride or Minoxidil before a hair transplant?+
Finasteride is usually continued right through the surgical process — stopping is not typically required, though Dr. Arslan will tell you if your case needs a brief pause. Topical Minoxidil should not be applied to the donor or recipient area for about a week before surgery, and is usually resumed one to three months afterward once Dr. Arslan confirms the timing is right for your healing stage.
Why do I see more shedding when I first start Minoxidil?+
Minoxidil pushes resting (telogen) hairs out early to make room for new anagen growth. This initial shedding phase is temporary, typically easing within a few weeks, and is a sign the treatment is activating the follicle cycle — not a sign it is failing. Finasteride does not cause this effect, since it works by preventing further miniaturisation rather than cycling the hair follicle.
