The most effective treatment at Norwood 4 is a hair transplant of 2,500 to 3,500 grafts combined with finasteride to stabilize remaining hair, though several non-surgical and combination approaches can also produce meaningful improvement. Here is every viable option ranked by effectiveness, cost, and suitability for this stage of hair loss.

Surgical Options
Surgery is the only treatment that physically replaces lost hair at Norwood 4. At this stage, the deficit is large enough that medication alone cannot restore a full-looking head of hair.
1. FUE (Follicular Unit Extraction)
FUE is the most commonly performed technique worldwide for Norwood 4 cases.
- Grafts per session: Up to 5,000
- Scar type: Dot scars, 0.7 to 1.0mm each
- Recovery: 7 to 10 days
- Graft survival rate: 90 to 95%
FUE extracts individual follicular units from the donor area using a micro-punch tool. The small, scattered dot scars are nearly invisible once healed, making this a good choice for patients who wear their hair short on the sides. A single FUE session can comfortably handle the full Norwood 4 graft range of 2,500 to 3,500.
2. FUT (Follicular Unit Transplantation)
FUT removes a strip of tissue from the donor area and dissects it into individual grafts under magnification.
- Grafts per session: Up to 4,000
- Scar type: Linear scar
- Recovery: 10 to 14 days
- Graft survival rate: 90 to 95%
FUT yields slightly more grafts per session from a smaller donor footprint, which makes it useful for patients who may need multiple sessions over their lifetime. The tradeoff is a linear scar at the back of the head. This is easily concealed by hair longer than about 2 centimeters but visible with a very short buzz cut.
3. DHI (Direct Hair Implantation)
DHI uses a Choi implanter pen to simultaneously create the recipient site and place the graft in one motion.
- Grafts per session: Up to 3,500
- Scar type: Dot scars, 0.7 to 1.0mm
- Recovery: 7 to 10 days
- Graft survival rate: 90 to 95%
DHI offers precise angle and depth control, which is particularly beneficial for hairline design at the frontal zone. Its main limitation is a lower maximum graft count per session. For Norwood 4 patients needing the full 3,500 grafts, DHI pushes against its per-session ceiling.
Surgical Cost by Location
| Location | Cost per Graft | Norwood 4 Range (2,500 to 3,500 grafts) |
|---|---|---|
| Turkey | $1 to $2 | $2,500 to $7,000 |
| USA | $4 to $6 | $10,000 to $21,000 |
| UK | $3 to $5 | $7,500 to $17,500 |
| Europe | $2.50 to $4.50 | $6,250 to $15,750 |
| India | $0.50 to $1.50 | $1,250 to $5,250 |
| Thailand | $1.50 to $3 | $3,750 to $10,500 |
| Mexico | $2 to $4 | $5,000 to $14,000 |

Medication Options
Medication does not replace lost hair the way surgery does, but it plays a critical role in stabilizing the hair you still have. At Norwood 4, medication is best used alongside a transplant to protect the investment.
4. Finasteride (Propecia, Generic)
Finasteride is the most clinically validated oral medication for androgenetic alopecia.
- Dose: 1mg daily
- Efficacy: Halts further loss in 80 to 90% of men, produces visible regrowth in about 65%
- Side effects: Sexual side effects in 2 to 4% of users
- Onset: Stabilization within 3 to 6 months, visible regrowth at 6 to 12 months
At Norwood 4, finasteride will not regrow enough hair to eliminate the need for surgery. Its primary value is protecting the native hair that remains, particularly in the mid-scalp and crown. Without finasteride, the hair behind a transplanted hairline will continue to thin, eventually creating an unnatural island of transplanted hair surrounded by continued loss.
5. Dutasteride (Avodart, Off-Label)
Dutasteride blocks more DHT than finasteride and may produce slightly stronger results in some patients. It is prescribed off-label for hair loss.
- Dose: 0.5mg daily
- Efficacy: Slightly higher than finasteride in head-to-head studies
- Side effects: Similar profile to finasteride, potentially at slightly higher rates
Dutasteride is typically reserved for patients who do not respond adequately to finasteride. It is not a first-line treatment in most clinical guidelines.
6. Minoxidil (Rogaine, Generic)
Topical minoxidil promotes blood flow to hair follicles and extends the growth phase of the hair cycle.
- Formulations: 2% and 5% topical solution or foam
- Efficacy: Moderate regrowth in 40 to 60% of users
- Onset: 4 to 6 months for visible changes
Minoxidil is most effective in the crown area. At Norwood 4, it serves as a supporting treatment that can improve density in areas where native hair is thinning but not yet gone. It pairs well with both finasteride and surgical treatment.
Non-Surgical Procedures
7. PRP (Platelet-Rich Plasma)
PRP involves drawing the patient's blood, concentrating the platelets, and injecting them into the scalp.
- Cost: $500 to $2,000 per session
- Density increase: 30 to 40% in responding patients
- Protocol: 3 to 4 initial sessions, then maintenance every 6 to 12 months
PRP works best for patients with thinning hair rather than completely bald areas. At Norwood 4, PRP can improve the density of miniaturized hairs in the transition zones but cannot regrow hair in fully bare areas.
8. Low-Level Laser Therapy (LLLT)
LLLT uses red light at specific wavelengths to stimulate follicular activity.
- Devices: Laser caps, combs, helmets
- Evidence: Modest density improvements in clinical trials
- Best for: Early-stage thinning, post-transplant recovery support
At Norwood 4, LLLT is a supplementary tool rather than a standalone treatment. Some patients use it to support graft survival and native hair health after a transplant.
Combination Strategies for Norwood 4
The most effective approach at this stage combines multiple treatments. Here are three common strategies:
Conservative Approach (No Surgery)
Finasteride + minoxidil + PRP. This combination can slow progression and modestly improve density in thinning areas. It will not restore the frontal hairline or fill fully bald zones. Best for patients who are not ready for surgery or want to stabilize before committing.
Standard Surgical Approach
FUE or FUT (2,500 to 3,500 grafts) + finasteride. This addresses the visible deficit surgically while protecting remaining native hair medically. Most Norwood 4 patients choose this route.
Maximum Restoration Approach
FUE or FUT (2,500 to 3,500 grafts) + finasteride + minoxidil + PRP. This combination provides surgical restoration, medical stabilization, and supplementary density improvement. It offers the highest probability of a full, natural result and long-term maintenance.
Choosing the Right Treatment Path
Your decision depends on budget, tolerance for medication, age, and how aggressively your hair loss is progressing. Younger patients (under 30) at Norwood 4 may benefit from starting medication first to gauge their response before committing to surgery.
