Predicting a Hair loss pattern in a 23 year old

I’m 23 with a Norwood 5 is it possible I never in my life reach Norwood 7? can I stop at a Norwood 5 or 6?

I would have to examine your donor fringe area to see if there is miniaturization around the fringe indicating a Class 6 or 7 pattern. Also, at age 23, the pattern may not have declared itself. As you get older, you may find that pattern emerging, see here: https://baldingblog.com/need-master-plan-think-hair-transplants-photos/.  Also the HAIRCHECK test is a valuable test to predict hair loss patterns before you can see them here: https://baldingblog.com/haircheck-test-how-it-is-done-video/. The advantage of this approach is that you buy time, time to see where your end balding pattern will develop, time to develop the money to do it right when you have a job that is secure, time to work through a Personalized Master Plan in tying to get your hair back while you wait with medications and possible microneedling.  Rushing only depletes your donor area way before you are ready.
