Weird bald lines 4-5 days after hair transplant? (Photo)

You have excessive scabbing.  It is best to go back to see your doctor so your doctor can help you clean your scalp.

didi234,Relax, do not worry about these demarcations in the transplanted area. Most if not all of the grafts can be lost in the next several weeks. It is entirely normal  and expected that many if not most transplanted grafts may be temporarily lost. Look closely because usually the skin includes part of the shaft but not the bulb. Whatever is still growing after 30 days is not likely to shed. Shedding is normal and the grafts will re-start to grow within the next few months. Growth can be accelerated with PRP treatment and the time of the procedure. Please check with your surgeon for the follow up care.

I believe you are referring to the breaks in the scabbing. There is a significant amount of scabbing, which will come off within the next few days. Once the scabs come off, the lines you mention will likely disappear.

Those are normal appearance after early phase of surgery . You may start to wash your transplant area at second day of surgery with care and massage the transplant area gently so the scabs will fall off... After two weeks of hair transplantation  it is acceptable  to wash hairs as normal /preoperative period of surgery. All scabs should be cleaned with pressured (not gentle) massage to transplant area  after 2 weeks .Dont forget that you may wash your head with normal pressure and if you need you can use a wet towel with soap for massage the scabby area, it Works very well to remove scabs .Patient may feel free to loosen any scabs on his/her head by massaging and that will not  damage the grafts after 2 weeks . 

These are terrible crusts that came from blood in the recipient area which should have been washed off the day of the surgery and every day thereafter.
