Is this a dense hair transplant? I undergone FUE with only 700 grafts. (Photos)

Hair transplant is not about how many grafts you need but understanding your goals and expectations. 2000 grafts may be enough for some but may not be enough for you if your expectations are different. The results also depend on your hair color to skin color contrast, hair texture, hair style, etc.It is best to follow up with your surgeon to discuss your surgery and expectations.

im not quite sure by the post op pictures however you will have to wait at least 6-12 months to actually see how it grows in.Truth be told and in my opinion I would have gone with more density in the areas that are treated in this post op picture. Probably up to 1200-1500.

Hairlines should be irregular with multiple peaks to achieve the irregularity and thus a more natural appearance.   A row of singles should be placed in the very front to achieve this.  In your case, about 300 grafts should be allotted just for that since you have a few going into the temple region. Behind those singles, 2's and some 3's are densely packed with an attempt at achieving 40% density. By the fact that you asked about density leads one to believe that you would like more grafts in the front. You should express your concerns to your surgeon.

It is difficult to answer your question from the photo that you are showing but it is clear you feel that this is not enough so go back and meet with your surgeon and discuss this
