The arrows point to the sites where the skin or the scalp died off. The second photo shows the scalp skin has sloughed off. The cause of this is often too much epinephrine in the local anesthesia and site that are made too close for recipient area or even possibly too large a site creation. This will cause a scarred area with no hair growth in it. You need an experience surgeon and team to avoid this. In my 32 years in practice with over 17,000 surgeries done by either me or my group, there has never been such a complication as shown here.
