This hair loss question was answered by Dr. Robert True of New York, NY who is a member of the Coalition of Independent Hair Restoration Physicians. His professional answer is below.
I just had surgical hair restoration and my hair is starting to fall out. Is this normal?
For almost all hair transplant patients, the transplanted hair falls out gradually from two to four weeks following transplantation.
During this short period of time, some of the hairs actually grow before falling out. Sometimes the hairs come out when the crusts/scabs fall off the skin (attached to the crust) or they may remain to fall out later. Rarely, some of the hairs may not fall out and will continue to grow without interruption. (This is not a problem – you can cut the hairs if you want)
