There can be exceptions to shock loss, but it is best to expect it to occur. Sometimes the trauma can result in shock loss of some of the native hair (i.e. hair we did not transplant) but it is expected to grow back unless it was about to fall out due to genetics. And, genetics can be combated with the use of finasteride. Dr. Keene is very careful to avoid transecting any existing hairs when she transplants hairs in between them, but trauma occurs with any incision and any surgery. So while the risk is minimized for temporary shock loss, it may still occur–so don’t panic if it happens! It will typically start to grow back within a few months. This transitional phase after surgery is the hardest part, but the wait is worth the results.
