Day 5 after hair transplant. I am worried by the lines I have. Is it normal? (Photo)

Thank you for your question. Sorry that you are worried. 
I would like to clarify a few things first - 
1) Did you have FUE or FUT ? HOw many hairs were transplanted overall - it looks like 2500- 3000.
2) The area where they implanted the hair - did you have any of your existing hair there?
3) When you had shaved your hair previously,had you noticed any scars on your scalp or are you aware of any scars on your scalp.
4) had you worn anything on your scalp following the hair transplant - woollen hat? 
5) what were your post operative instructions? 
It is only one week following the surgery and it does look like you have good coverage. The scalp does swell up and it might well be that certain parts of the scalp are still quite swollen. As this swelling settles down it may well reduce the distance between the grafts in this area. Your final result will not be apparent for at least 18 months and in the first month there can be shedding of not only the transplanted hair but if there was some exisitng hair in these areas then they can go into shock and shed. This is not a worry as it all tends to grow back as the hair bub is still embedded. 
I can see why you have a concern as it does seem like no hair has been placed there. It would be easier to see in person - Have you contacted your surgeon and requested a review? It would be useful to go back to him/ her and enquire as to whether any hairs were placed there or not. From the picture it is not obvious to me if there are any holes for the grafts to have been implanted or not. 
I hope this helps you with your concerns

It is best to contact your doctor about post operative care and instructions since each doctor has a different regimen.  You may not be washing your hair and scalp as instructed.

In my opinion everything looks normal. I do not see evidence of any issues of the scalp on this photos but you should get your surgeons opinion as well. Some people have more scabs than others. It just depends.
