Why does hair shedding sometimes occur after hair transplant surgery?
The hair loss that people experience 10-20 days after hair restoration surgery is not a telogen shed. It is more of an anagen arrest and shedding of hair as a direct result of the inflammation/trauma caused by the creation of hair transplant recipient sites. While we currently try to minimize this by making sites that are 6-9 mm in size coupled with oral prednisone, shedding can still occur.
My father, Dr. Bobby Limmer, has seen some promising results (diminishing this shed) by using very dilute kenalog (cortisone) within the anesthesia we inject into the recipient zone to numb the area. While promising, we have not fully changed over our solution at this time.
