Q: It has been over a month after my hair transplant procedure and I am starting to get nervous. When can I expect to see some growth? — J.N., Winnetka, I.L.

A: Transplanted hair begins to grow, on average, about 10 weeks after the procedure, although this number can vary. Hair tends to grow in waves and occasionally some new hair may start to grow as long as a year after your procedure. In general, growth is a bit slower with each hair transplant procedure, although the reason for this is not fully understood.
