The Norwood Classification in hairloss... Hairtech


This thread is for the education of ghost readers. Most veteran posters know this. The chart below is a simple way to classify a persons hairloss. This chart is found on most hair transplant doctor’s websites as well as used in determining hairloss on most industry website forums. Simply put, when O’Tar Norwood, M.D. wanted to diagnose his patients hairloss, he would state, “He is a Norwood Class X”

X is where the hairloss is on the chart. Some posters abbreviate this by
NW I,II, III, etc.
