Male pattern baldness is the most common type of hair loss in men. Understanding the Norwood Scale a standardized classification system helps individuals and professionals gauge progression and choose appropriate interventions. In this guide, we explore every stage, review the science, and outline evidence based treatments.
in hair restoration.
What are the 7 Stages of Hair Loss?
Norwood Stage 1
- Description: Minimal or no recession of the hairline.
• Visual Cue: A juvenile, full hairline.
• Action: No treatment typically required; healthy lifestyle and scalp care advised.
Norwood Stage 2
- Description: Mild temporal recession forming a subtle M‑shape.
• Risk: Early androgen sensitivity begins.
Can my hair stop receding at Norwood 2?
Yes—if genetics are favorable and preventative care (e.g., DHT‑blocking shampoos, balanced nutrition) begins early.
Norwood Stage 3
- Description: Deeper frontal-temporal recessions; hairline forms a pronounced M or V.
What should I do if I have a Norwood 3 hairline?
Initiate medical treatments (minoxidil, finasteride) and consider Low‑Level Light Therapy (LLLT) for preservation.
Norwood Stage 3 Vertex
- Description: Moderate vertex (crown) loss while frontal hairline may remain Stage 2 or 3.
Norwood Stage 4
- Description: Significant frontal recession plus a distinct bald spot on the crown, separated by a bridge of hair.
Norwood Stage 5
- Description: Bridge thins; frontal and vertex bald areas enlarge.
Norwood Stage 6
- Description: Front and crown merge; only sparse hair on sides remains.
Norwood Stage 7
- Description: Most severe stage; horseshoe fringe of hair on sides/back only.
Treatment Options for Norwood 2–4
| Stage | First Line Options | Adjuncts |
|---|---|---|
| Norwood 2 | Topical minoxidil, DHT blocking shampoo | Microneedling, LLLT |
| Norwood 3 | Minoxidil + finasteride | PRP, pumpkin seed oil |
| Norwood 4 | Oral finasteride, LLLT cap | Small graft FUE transplant |
Treatment Options for Norwood 5–7
| Stage | Recommended Procedures | Maintenance Therapy |
|---|---|---|
| Norwood 5 | Large session FUE or FUT transplant | Oral finasteride, LLLT |
| Norwood 6 | Multi-session FUE + scalp micropigmentation | Finasteride + dutasteride (off-label use) |
| Norwood 7 | Scalp micropigmentation, hair systems | Lifestyle changes, topical concealers |
How is Male Pattern Baldness Diagnosed?
Diagnosis involves:
- Medical history (family hair‑loss patterns).
- Physical exam (miniaturization via dermoscopy).
- Norwood Scale staging.
- Lab work (hormone, thyroid panels) if atypical shedding observed.
How to Treat Male Pattern Baldness
Treatments for male pattern baldness include:
1. Over‑the‑Counter Treatments
• Minoxidil foam/solution
• Ketoconazole shampoo
2. Laser Treatment (LLLT)
• FDA‑cleared caps or combs
• 3–4 weekly sessions, 15 min each
3. Prescription Medications
• Oral finasteride 1 mg daily
• Oral dutasteride (off‑label)
4. Procedures
• Micropigmentation
• Hair transplant (FUE, DHI)
• Scalp reduction surgery
• Scalp expansion or tissue‑extender
• Micro‑Needling + growth serums
• Platelet‑Rich Plasma (PRP)
5. Lifestyle Changes
• Balanced diet rich in zinc, biotin, vitamin D
• Stress management (mindfulness, exercise)
• Avoid tight hats, reduce heat styling

How is Hair Loss Treated?
1. Over‑the‑Counter Treatments
Minoxidil
Enhances blood flow, extends anagen phase.
Laser Devices
Promote ATP in follicle cells.
2. Prescription Treatments
Finasteride, dutasteride, topical corticosteroids (if inflammation).
3. Procedures
FUE, scalp reduction, expansion, micropigmentation—detailed above.
Reasons for Hair Loss
Genetics, hormonal shifts, nutritional deficiencies, chronic stress, autoimmune diseases, medications, and tight hairstyles.
Treating and Preventing Hair Loss
Early intervention is key: combine medical therapy, lifestyle modification, and, when needed, surgical solutions.
What Causes Male Pattern Hair Loss?
Androgenetic alopecia stems from genetic sensitivity of hair follicles to DHT, leading to miniaturization and shorter growth cycles.
Is There a Way to Prevent Male Pattern Hair Loss?
While genetics can’t be altered, preventative care—finasteride, minoxidil, balanced nutrition, and scalp health—can slow or halt progression.
How the Norwood Scale Can Help You Choose the Right Hair Loss Treatment
Assessing your stage pinpoints appropriate interventions: e.g., Norwood 2 may only need topical solutions, while Norwood 6 likely requires transplantation combined with oral therapy.
