What is my hair loss pattern on Norwood Scale? (photo)

I have marked up the areas that are thinning that may lead to complete balding. The forelock has a different genetic code and may remain in some men so this man has an evolving Norwood Class 5 pattern that could eventually lead to a Class 6 pattern as many such patterns do. You have at this time a persistent forelock that may eventually be lost along with the bridge area defined in the photo as well. If you are lucky and the forelock lasts until you are 35, it will hold a frame to your face for many years after
