Chance I am a Norwood 6/7? If not, am I good candidate for a hair transplant? (photos)

Hair loss has many causes, including stress, medications, autoimmune, genetic, trauma, etc. Medical treatments can work and options would include finasteride (propecia), minoxidil (rogaine), PRP (platelet rich plasma), laser light therapy, and vitamins. It is often uncertain which medical therapy will help which patient and so a combination of therapies is typically recommended to maximize benefit. A hair transplant is a surgical option and is appropriate for certain conditions and individuals. 
The goal of a hair transplant is to provide fuller coverage while preserving a natural appearance. An assessment takes into account such factors as the apparent thickness and curl of your donor hairs, the color contrast between your scalp and hair, your hair loss pattern, your age, and many other factors. The state of the art technique is FUE (follicular unit extraction), performed with a hybrid blunt punch that minimizes graft transection while allowing for the use of the smallest possible punches to minimize donor site scarring while maximizing regrowth.
In your situation, I would recommend a procedure of 1200 FUE grafts to the frontal temporal areas, maintaining a natural recession point. It is difficult to tell exactly where you will end up on the Norwood scale down the road, but you do appear to have quite a bit of hair at this time which is great.

Based on the photo attached, you are currently at Norwood grade 3. The ideal treatment for hairline and temporal recession would be hair transplantation. I would advise you to seek a hair transplant surgeon in your area for follicular hair extraction (FUE) and you would need around 1200 -1500 grafts.
There are many modalities to prevent further progression of male pattern hair loss if you are not ready for oral finasteride. These including PRP, Regenera Activa, topical minoxidil and low-level laser therapy. Do consult a hair transplant specialist to discuss your options.

Your situation  is norwood 3 and ıf we calculate balding agresiveness index,  your score is  lower than 1 that means you  will  have a very good donor area nad hev no  problem about supply . I dont think  so  that you  would end with  grdae 6 or 7 norwood  baldness. But any way, FUE hair transplant can be an option for forehead reduction,  correcting  receding hair line and asymmetry on your frontal hair line/forelock. I advice you have a FUE with 1800-2000 grafts; you would achieve the desired hairline in just one session of dense packing hair transplant.
