Will I become a Norwood 7 or will I stay as a Norwood 6?

Hair loss pattern in multifactorial. Genetics, age and generalized health all play a role. Predicting a pattern is difficult but becomes easier (and more accurate) with age. A thorough clinical and family history can help one develop an educated guess as to where they will plateau. Older patients who look similar to their male family members are more likely to stabilize than are younger patients with significant familial disparity. That being said, this is only a guess and early intervention can turn the tide.As always, discuss your concerns with a board certified plastic surgeon (ABPS) with experience in hair restoration.

Your hair loss will progress to some degree and the speed of progression will depend on the your underlying genetics and how much you respond to treatment. But in all likelihood there will be some worsening over time. See a physician to discuss that plan over the next 75 years.

You are only 24 and it is hard to say when your hair loss will taper off and stabilize.  You should be seeing a dermatologist for treatment.  Oral finasteride will be helpful and PRP treatments should also help to regrow and thicken hair.  Lasers and hair transplants are also possibilities for you. This is 2019 and many options exist for treatment for you.  

You must plan on becoming a Class 7 because if you are planning a hair transplant, the end result will depend upon a good Master Plan for your hair loss reconstruction
