Norwood Scale for Hair Loss Grading / Stages

Understanding the Norwood Scale

The Norwood Scale is a widely used classification system for diagnosing and describing the stages of male pattern baldness. It helps in assessing the extent of hair loss and planning appropriate treatment options.

How is Male Pattern Baldness Diagnosed?

Typical male pattern baldness is usually diagnosed based on the appearance and pattern of hair loss, along with a detailed medical history. Questions about the prevalence of hair loss in your family are also considered.

The Norwood Scale Stages

The Norwood Scale consists of several stages that depict the progression of hair loss:

  1. Stage 1: No significant hair loss or recession of the hairline.
  2. Stage 2: There is a slight recession of the hairline around the temples.
  3. Stage 3: The first signs of clinically significant balding appear. The hairline recedes at the temples to form an M, U, or V shape.
  4. Stage 4: The hairline recession is more severe than in stage 3, and there is sparse hair or no hair on the vertex (top of the scalp).
  5. Stage 5: The areas of hair loss are larger than in stage 4. There is still a small strip of hair separating the two areas of hair loss.
  6. Stage 6: The strip of hair separating the two areas of hair loss is almost gone, leaving a larger bald area.
  7. Stage 7: The most severe form of hair loss, with only a band of hair remaining on the sides and back of the scalp.

Importance of the Norwood Scale

This chart of hair loss grades and stages is a useful tool for diagnosis and to avoid misdiagnosis. It helps in describing the extent of hair loss for treatment purposes. There may be times you will have to relay this information via telephone or the Internet to physicians or practitioners from whom you are seeking information.
