What happened to my hair transplanted scalp? (photo)

You had scalp necrosis, usually the cause of technical issues in instrumentation and judgments made by the doctor. When the recipient sites are made with a larger instrument and/or they are placed too close to each other, especially in the area between the ears in the center of the scalp where your problems are showing, necrosis may occur. This will take sometime to heal. Find a doctor who knows how to manage wound problems.
