This hair loss question was answered by Dr. Glenn Charles of Florida who is a member of the Coalition of Independent Hair Restoration Physicians. His professional answer is below.
One thing I never really understood is when people say that the hairline will soften during the period 6-18 months after a hair transplant. I thought that hairs initially grew thin and thickened up during this same period. If hairs are getting thicker how can the hairline get softer? What does softening of the hairline actually mean?
Creating a soft and natural hairline with surgical hair restoration should be addressed by the hair replacement surgeon during the procedure.
It is critical that the thinner/finer hairs be used in the hairline. Thick/coarse hairs will most likely have a similar look and feel no matter where it is placed. It is true that sometimes transplanted hairs will be more brittle and kinky during its first hair growth cycle. After repeated hair growth cycles and hair cuts those same hairs might begin to look and feel softer, but are probably just finally returning to their original state.
