Hair line still looks too high after Transplant, can another procedure achieve this or am I being unrealistic? (photos)

If you are not happy with the results after a surgery it is best to follow up with a doctor to understand your options.  Your surgical results partly depend on good communication between a doctor and the patient.

That depends on a variety of factors, most importantly your donor area. You simply may not have a thick enough donor area to get a reasonable density over such a large area of your scalp. In general it is better to be conservative with transplants to avoid over harvesting or just making a hairline that's too low, and neither of those issues can be easily solved. Talk to your doctor about the possibility of having a second procedure if you are still worried, you will probably have to wait until you've seen the final results of this one first.

if anatomy of the forehead scalp is feasible to having a lower frontal hair line, you may have it. I advice you have a FUE; you would get the desired hairline in just one sesssion of dense packing hair transplant. Hair grafting/ transplant can be an option or forehead reduction and correcting  asymmetry on your frontal hair line/forelock.

It's easy to lower a hairline, but extremely difficult to raise a hairline (i.e. correcting a hairline that was placed too low by prior surgery). I would give it at least 6 months before you make your final judgement on the hairline. If it still bothers you after 6-12 months, you can consider lowering/adjusting the hairline at that time (assuming you have available donor hair). I recommend following up with your hair surgeon if you have any concerns.

Certainly, in the future you can change you hairline.  I personally do not think the overall location or contour is bad, but you do have a sharp point that is a bit off center (at least in the photos).  I do recommend growing you hair out to you desired length.   If you are going to have it longer, these concerns will likely never be seen. 

if you are going to continue to wear your hair short or wear it combed back, that might bother you. If you wear it down, you won't notice much. Give it at least 6 months and reassess. It wouldn't take many grafts to make an adjustment. Good luck!

A male hairline should be located one finger breath above the highest crease in the furrowed brow.  If you lift your eyebrows and crease your brow, the hairline location is best determined by this finger rule,
