Thinning hair and balding are common occurrences, but they don’t appear the same way for everyone. Recognizing the type of hair loss is a patient’s first step to determining the right treatment plan.
The Norwood Scale groups male baldness into seven different classes.
Class 1 represents a normal head of hair with no visible hair loss.
Class 2 is characterized by the beginning of a receding hairline and a “widow’s peak” on the forehead.
Class 3 patients exhibit a more significant decline in hair above the temples as well as receding from the forehead. In Class 3 Vertex, hair loss is starting to become significant on the crown.
Class 4 hair loss may become more noticeable on the crown or patients may have significant hair loss above the temples and/or front anterior areas.
Class 5 hair loss approaches significant levels with most hair loss occurring on the top of the vertex and crown. Hair transplantation for this Class and higher Class levels may require more grafts to provide coverage and density.
Class 6 patients show major hair loss, but still have areas with donor hair available. Transplanting this hair can still have excellent results.
Class 7 patients show the most significant loss of hair. There may still be sufficient donor hair for transplantation; however, results may be limited.
The Ludwig Scale classifies female baldness by three different types.
Type 1 female baldness is the least severe with thinning on the top of the head.
Type 2 hair loss in women is more significant with areas of the scalp showing through thinning hair.
Type 3 patients may completely lose hair on the crown of the head. In this case, more donor hair will be required to obtain full coverage.
