The Norwood scale: A guide to male pattern baldness (2024)

Male pattern baldness, known in medical terms as androgenetic alopecia, is a common problem affecting men of all ages. It involves the gradual thinning of hair and can eventually lead to complete hair loss on certain parts of the head. One of the most widely used methods to accurately measure hair loss in men is the Norwood scale. Let's look at what this scale entails, how it is used and what solutions we offer for men with hair loss at different stages.

What is the Norwood scale?

The Norwood scale is a classification system used to measure and categorise male pattern baldness. First developed by Dr James Hamilton in the 1950s, the scale was later revised by Dr O'Tar Norwood in the 1970s and this version is most commonly referred to today. The scale is made up of seven different phases, each representing a specific stage of hair loss.

The stages of the Norwood scale

• Phase one: In this phase, hair loss is minimal and the hairline is not visibly receding.
• Phase two: There is hair loss around the temples, but this is not yet significant and is often considered a normal, mature hairline.
• Phase three: Hair loss becomes noticeable, with a deep retreat of the hairline at the temples, giving it an M, U or V shape. The hair becomes thinner and baldness becomes visible.
• Phase four: Hair loss is now clearly visible along the top of the head, although a thin hairline is still present separating the two areas.
• Phase five: Baldness is more evident, with residual hair on the sides and back of the head, and a thin and sparsely hairy strip on top.
• Phase six: The individual areas of hair loss are no longer separated by a band of thinning hair.
• Phase seven: This is the final stage of the Norwood scale, where the remaining hair on the head looks like a band running around the sides and back of the head. The hair may be thin or sparse.

Using the Norwood scale

The Norwood scale is of great value to dermatologists for measuring male pattern baldness. By accurately measuring the degree of hair loss with this scale, they can offer personalised treatments to suit each patient's specific needs. For patients themselves, the Norwood scale is also a useful tool to understand the severity of their hair loss and make informed decisions about possible treatments.
