Dr. Savin from Yale University developed the scale (savin scale) for classifying women’s hair loss named after him in 1992.
Dr. Savin and his colleague Dr. Tanick suggested nine computer images to classify hair loss. Their classification proved to be very effective and detailed. When different researchers used the scale, they could assess the same results in the scale. The scale provided a standardization in the classification of women’s hair loss. It added subcategories to the previous scales.
Neither Ludwig Scale nor the Savin Scales addresses the progressive frontal hair loss, also known as Christmas tree pattern.
The Savin Scale has three stages, and nine phases

Images II-1 to II-2: Diffuse thinning on the top of the scalp.
Image III: More diffuse thinning on the top of the scalp.
