Question 1

What is the Norwood Scale?

Accepted Answer

The Norwood Scale (also known as the Hamilton-Norwood Scale) is the leading classification system for measuring male pattern baldness (androgenetic alopecia). Originally developed by Dr. James Hamilton in the 1950s and later refined by Dr. O'Tar Norwood in the 1970s, this internationally recognized Norwood Scale chart ranges from Stage 1 (minimal hair loss) to Stage 7 (most severe), helping dermatologists and patients understand the progression of hair loss. The Norwood Scale is currently the most widely used system by hair transplant surgeons and trichologists worldwide.

Question 2

What are the 7 stages of the Norwood Scale?

Accepted Answer

The Norwood Scale stages progress from minimal to severe hair loss: Stage 1 shows no significant hair loss; Stage 2 displays slight recession at the temples; Stage 3 marks the beginning of clinical baldness with an M-shaped hairline; Stage 4 shows further recession with sparse hair on the crown; Stage 5 presents a wider bridge of hair loss; Stage 6 sees the temple and crown areas merging; Stage 7 represents the most advanced form with only a horseshoe-shaped band of hair remaining. The Norwood Scale also includes Type A variants for different hair loss patterns.

Question 3

How accurate is the Norwood Scale AI assessment?

Accepted Answer

Our Norwood Scale AI assessment leverages cutting-edge multimodal AI technology with advanced reasoning capabilities to evaluate your Norwood Scale stage. The system examines your hairline according to established Norwood Scale criteria—including temple recession patterns, frontal hairline shape, crown thinning severity, and overall progression indicators—to provide an accurate Norwood Scale diagnosis. This reasoning-based approach allows our Norwood Scale assessment to not only classify your stage but also explain the specific Norwood Scale features present in your hair loss pattern, making it more transparent and educational than traditional automated Norwood Scale tools. As with any AI-based Norwood Scale evaluation, this tool is designed for informational screening and should complement, not replace, professional consultation.

Question 4

Is Norwood Scale Stage 2 or 3 reversible?

Accepted Answer

While complete reversal isn't possible, early Norwood Scale stages (2-3) respond well to treatment. Medications like finasteride (which reduces DHT levels) and minoxidil (which stimulates hair growth) can effectively slow or halt progression and may restore some hair density. Medical studies show that treating hair loss at Norwood Scale Stage 2 or 3 offers the best chance to maintain a natural look. PRP (Platelet-Rich Plasma) therapy combined with finasteride can be particularly effective for Norwood Scale 3 vertex patterns.

Question 5

How do I know my Norwood Scale level?

Accepted Answer

You can determine your Norwood Scale level by comparing your hairline pattern to the Norwood Scale chart or using our AI-powered assessment tool. Our system analyzes photos of your hairline from multiple angles (top and side views) to accurately classify your hair loss stage. The assessment examines key indicators including temple recession depth, hairline shape, and crown thinning patterns.

Question 6

Can women use the Norwood Scale?

Accepted Answer

The Norwood Scale is primarily designed for male pattern baldness, as men typically experience hair loss through temple recession and crown thinning. Women usually experience different hair loss patterns—diffuse thinning across the crown while preserving the frontal hairline—which is better classified using the Ludwig Scale. However, in rare cases where women exhibit male-pattern baldness characteristics, the Norwood Scale may be applicable.

Question 7

Is my data private and secure?

Accepted Answer

Absolutely. We do not require registration. Your photos are processed securely using encrypted connections and are not stored on our servers. Our project is open-source on GitHub, ensuring full transparency in how we handle your data. If you want complete control over your data and privacy, you can also choose to self-host our open-source project on your own infrastructure.

Question 8

Do I need to create an account?

Accepted Answer

No, you can use our Norwood Scale assessment tool completely anonymously without creating an account. We believe everyone should have free access to professional-grade hair loss evaluation. If you want to save your Norwood Scale assessment results and photos for long-term monitoring of your hair loss progression, you can choose to have the results and photos sent to your email. We do not store your email address.

Question 9

What should I do after getting my Norwood Scale results?

Accepted Answer

Your Norwood Scale results will include personalized recommendations based on your specific stage. For early stages (Norwood Scale 1-3), lifestyle changes and preventive treatments like minoxidil or finasteride may help slow progression. For more advanced Norwood Scale stages (4-7), we recommend consulting with a dermatologist or hair restoration specialist to discuss treatment options such as hair transplant surgery, PRP therapy, or advanced medical treatments.

Question 10
