Doc,
I’m confused bout the difference between the Norwood 2 and the Norwood 3 with a persistent forelock. Can you clear this up for me?
A Norwood Class 3 hair loss pattern has more recession of hair on the front corners. “Persistent forelock” just means you have a strong (non-balding) area of hair in the front middle, which on many people will actually go down as far as the highest crease in the wrinkled brow. Most Norwood 2 or 3 patients have a good, strong (non-balding) front middle hair zone. I wrote a bit about comparing Norwood 2 and 3 at Juvenile vs Mature Hairline — Am I Going Bald?.
