Hairloss looks different for everyone, but for men, there’s a widely used system that helps describe and track the progression of genetic hairloss: the Hamilton–Norwood Scale. Whether you’re noticing early thinning or more advanced changes, understanding this scale can help you make sense of what you’re experiencing and explore the right solutions for your stage.
At HairLoss.com, our goal is to make information simple, approachable, and empowering. Here’s everything you need to know about the Hamilton–Norwood Scale and how it can guide your next steps.
What Is the Hamilton–Norwood Scale?
The Hamilton–Norwood Scale is a visual classification system used to measure male pattern hairloss (androgenetic alopecia). It includes seven stages, ranging from minimal recession to advanced hairloss.
It’s commonly used by dermatologists, hair restoration professionals, stylists specializing in hair replacement, and individuals tracking their own hairloss over time.
Knowing your stage can help you explore wigs, toppers, hair systems, and other supportive solutions with more clarity.
The Stages of the Hamilton–Norwood Scale
Stage 1: Minimal or No Hairloss
The hairline looks unchanged and recession is not visible. Most people do not notice any thinning at this stage.
Stage 2: Early Recession
A mild “M-shaped” hairline appears with slight thinning at the temples. This is usually when men first recognize changes. Early coverage solutions may include lightweight toppers or hair fibers.
Stage 3: Noticeable Frontal Hairloss
Recession deepens, forming a more defined M-shape. This is considered the first clinically significant stage of male pattern hairloss. Coverage options such as small toppers or light-density hair systems may be useful.
Stage 3 Vertex
Thinning begins at the crown, creating a small bald spot. Frontal recession may or may not be present. Crown-focused toppers or early-stage systems are often helpful here.
Stage 4
Both the front hairline and crown show noticeable hairloss, though a thin bridge of hair still separates the two areas. Medium-coverage solutions or partial hair systems work well at this stage.
Stage 5
The bridge of hair separating the frontal and crown thinning areas begins to break down. Hairloss becomes more widespread. Many individuals consider transitioning to fuller-coverage systems.
Stage 6
The front and crown merge into one large thinning area. Only the sides and back hold significant hair density. Full hair systems usually offer the most natural, seamless coverage here.
Stage 7
The most advanced stage, showing extensive hairloss with only a thin band of hair remaining. Full-coverage systems with breathable, comfortable bases are ideal for achieving natural results.
How the Scale Helps You Choose the Right Solution
Identifying your stage on the Hamilton–Norwood Scale can help you understand your pattern of hairloss, explore the best coverage options for your needs, set realistic expectations, and communicate clearly with stylists or hair replacement professionals.
It’s not a diagnosis — it’s simply a helpful guide.
