Find Your Stage, Find Your Plan

The Norwood-Hamilton scale classifies male pattern baldness from Stage I (no significant loss) to Stage VII (extensive loss leaving only a horseshoe pattern). Knowing your stage determines which treatments will work, which won't, and when to act.

~90%

success rate for halting progression when treatment begins at Norwood II–III

Source: Dermatology literature

Stage	Pattern	Treatment Options	Success Rate
NW I	No recession — mature hairline	Monitor only	N/A — no treatment needed
NW II	Slight temples recession	Finasteride ± minoxidil	Very high (90%+)
NW III	Deeper recession, crown thinning begins	Finasteride + minoxidil + microneedling	High (80%+)
NW IV	Significant recession + crown loss	Full stack + consider transplant assessment	Moderate (60-70%)
NW V	Connecting band thinning	Full medical stack + transplant likely needed	Limited for regrowth
NW VI	Only horseshoe band remains	Transplant ± medical maintenance	Transplant-dependent
NW VII	Extensive loss	Transplant + SMP + acceptance	Limited

Key Takeaway: Early intervention is everything. Finasteride at NW II has a ~90% chance of halting progression. At NW V, you're mostly playing defense. The best time to start treatment is before you think you need it.

Frequently Asked Questions

How do I know what Norwood stage I am?

Look at your hairline in a mirror under bright lighting. Compare to the Norwood scale illustrations. Temple recession without crown loss is typically NW II-III. If you're uncertain, a telehealth provider can assess photos.

Is it too late to start finasteride at NW IV?

No. Finasteride can still halt further loss at NW IV and may produce modest regrowth. But expectations should be realistic — you won't regrow to NW I. Adding minoxidil and microneedling maximizes results.

Should I get a transplant instead of taking finasteride?

Finasteride is essential BEFORE and AFTER transplant. Without it, native hair continues falling around transplanted grafts. Most transplant surgeons require patients to be on finasteride.
