Norwood scale

The Norwood scale is a system used by doctors to classify the stages of male pattern baldness. It helps describe how hair loss progresses, starting from minimal thinning to advanced baldness. The scale ranges from Type I, with little or no hair loss, to Type VII, where most of the scalp is bald. This classification helps in diagnosing hair loss severity and planning appropriate treatments or options, providing a common reference point for both patients and healthcare professionals.
