Is dead skin normal after getting a FUE hair transplant?

Each follicular unit is taken with a small piece of skin around it so that the hair root doesn’t need to be handled directly. This skin “collar” around the hair will often stick up a little, creating a bumpy appearance in the first month. When the hairs shed, they often will do so along with dried out skin from the part that was sticking up. At 3 weeks you should be ok to scrub a little harder to remove these areas, but avoid being aggressive so you don’t irritate your scalp. 

It is best to contact your surgeon for post surgery issues and care since all doctors have slightly different instructions.

Skin and hair can shed after the procedure starting few days after surgery and it can be normal. However, there is also possibility (if something went wrong) that there is necrosis of the scalp skin. You should check immediately with you surgeon

Sloughed skin can be normal as the implanted hairs can either start to shed during the first few weeks.  It is quite normal for implanted hairs to shed post procedure, but our early use of regenerative techniques has helped some of our patients retain hairs and realize results in a shorter period of time.  Consult with your hair surgeon to ensure your care is optimal post procedure.  Best Dr. Anil Shah

What you're experiencing is very normal. The dried blood and hairs typically begin shedding after 2 weeks. The hair bulb is what's really important and that has taken hold and stays in place. Apply shampoo and gently massage. They will slowly come off. Don't pick.Discuss your concerns with your surgeon for more information.
