Q: After my hair transplant procedure I had some shock loss, and then after about 4 1/2 to 7 months I had tremendous growth — really thick. I was amazed actually. Now, at 8 months it has thinned again, quite a lot compared to the growth I had before. I just wondered if this was a normal growth pattern and whether further growth could be expected? — N.T., Brooklyn, NY
A: This is not the most common situation, but should not be a cause for concern. The newly transplanted hairs are initially synchronous when they first grow in — i.e. they tend to all grow in around the same time (with some variability). This is in contrast to normal hair, where every hair is on its own independent cycle. Sometimes the newly transplanted hair will shed at one time before the cycles of each hair become more varied asynchronous.
