For what I can see the hairline looks fine, however I would like you to upload a picture of your donor 1 week after the procedure because what I see is a bit worrisome.
NW6 or NW7 is basically the same lol, you are bald in both cases, quit fin and go on with your life, take care of your health, of your diet and enjoy your life mate.
3 possible scenarios
1. You had native hair mixed with your transplanted ones, that is the hair that is falling
2. Your hair is just entering telogen phase before it grows out again(anagen phase)
3. Hair was either extracted from unsafe donor area or you have DUPA
1.The height of your hairline should be above all dependent on your donor
2. They usually count based on the second picture
My question is where is the glabela?
Is it the middle point of the middle of the brows or the middle point of the top of the brows?
