Norwood 7 quite extreme. Options? (photos)

Photos cannot determine if you would be a good candidate for surgery.  You need an examination and the doctor needs to understand your goals and expectations.

When planning a hair transplant procedure, we must always weigh a few factors: patient's goals and expectations, area of hair loss to be covered, quantity and quality of the available donor hair, possible/likely future hair loss, just to name a few. This is why hair restoration surgery is one of the most complex procedures.
Based on your pictures, the ratio between available donor area and recipient area is not favorable, meaning there is a lot of scalp to cover, and your donor area seems to have lower than average density overall. This would make it difficult to create results with any kind of density for you. At the most, you could have a conservative hairline and very thin coverage on the top of your scalp. If that would make you happy, then perhaps it could be done, but I would strongly recommend that you consult with a doctor who has extensive experience in hair restoration; not a novice. Your hair restoration strategy will likely require a combination of FUE and FUT to move more hair, but of course a detailed, in person evaluation of your hair would be required. 
Maybe the best thing for you will be to either wear a hair piece or shave your head, instead of venturing into hair transplants. 
Please be careful and do your research before signing on for a transplant.  
Best of luck!

We have seen many patients at this stage of hairloss and have found that the right combination of FUE hair transplants, PRP and Scalpmicropigmentation, we can get a really great result. The bad news is that you will never have a full head of hair again, but we can get you something pretty good. 

Losing hair can be very frustrating, however not everyone is a good candidate for hair transplant surgery no matter the donor method, either follicular unit excision or strip harvesting. Based on your photos you should see a well qualified hair transplant surgeon in person to assess your donor area and see if your expectations are achievable.

Hair transplants in a Class 7patient requires a very high donor density and if you are lucky to have that, you could have a good hair transplant result. Alternatievely Scalp Micropigmentation with a shaaved head is faster to get results and less expensive.
