Norwood Stage 4 represents advanced hair loss where severe frontal recession is accompanied by a distinct bald spot on the vertex (crown). These two areas of hair loss are separated by a solid band, or 'bridge,' of moderately dense hair across the top of the scalp. Full restoration typically demands 2,500 to 3,500 grafts.
The frontal 'M' shape has receded extremely deep, and the hair in the center forelock may be thinning. Simultaneously, there is a clear, visible circular bald patch on the crown. Crucially, a band of hair (the bridge) still firmly connects the sides of the head across the top.
At Stage 4, surgical planning becomes significantly more complex. Your surgeon must carefully extract grafts from the donor area to address both the extensive hairline recession and the crown bald spot without over-depleting your reserves. The preservation of the central bridge is crucial.
In the Norwood 4A variant, the hairline has receded past the mid-scalp, but there is no separate bald spot on the crown. The hair loss progresses entirely from front to back.
If left untreated, the hair in the 'bridge' separating the front from the crown will continue to miniaturize and thin out, eventually leading to Stage 5 where the two bald areas begin to merge.
2,500 – 3,500 Grafts
Because both the front and the crown need attention, the graft requirement jumps significantly. A standard Norwood 4 requires 2,500 to 3,500 grafts. Surgeons often allocate roughly 2,000 to the front and 1,000 to the crown. Read our comprehensive guide on How Many Grafts Do I Need? for more details on calculating your specific requirements.
The total cost of your hair transplant depends entirely on the clinic's location and pricing structure (per-graft vs all-inclusive package).

Surgical hair transplantation is highly effective here, but because the crown consumes many grafts, patients must manage their expectations regarding density. Aggressive medical therapy (Finasteride/Minoxidil) is heavily urged to preserve the fragile 'bridge' of hair.
Yes, 3000 grafts is usually sufficient for a Norwood 4, but the surgeon will likely prioritize creating high density at the hairline while offering lighter, natural-looking coverage on the crown.
Not at all. Norwood 4 patients are among the most common and successful hair transplant candidates, provided their donor area is healthy.
Finasteride is excellent at stopping further loss and may regrow some hair on the crown, but it will not regrow the slick-bald areas at the receded hairline. Surgery is required for the front.
Extracting and implanting 2,500 to 3,500 grafts typically takes a full day (6 to 8 hours) in a single session.
