I have about the straightest hair a guy could have. When I got my transplant (FU's), the transplanted hair seemed extremely wirey. In about 4 months, it fell out (no surprise there), but when it grew back in about 4 months, it perfectly matched the rest of my hair. No more wirey-ness! Some transplanted hairs are slightly darker, but not enough to stand out. I'm telling you, I dont think a hair dresser could tell I had transplants. The transplanted temples just look less dense than the rest of my hair.
Hope this helps.
