I'm not talking about contrast. I'm talking about the thickness of the hair strands. Blonde hair is very thin so it requires more hair strands to get the same amount of coverage. If you have dark hair you can bleach it if you want less contrast, but beyond a certain point in coverage the amount of contrast doesn't matter because there isn't any contrast. For optimal results you will get enough coverage that contrast isn't an issue. For a low density transplant blonde hair and light skin is good better than dark hair and light skin, but neither will look good. You can see below that black hair is twice as thick in diameter as blonde hair, so contrast aside they need 20k grafts to do what can be done with 10k grafts of black hair. Curly hair helps too. If it wasn't for the appearance scarring on black skin, black people would have perfect hair transplants.If you have light skin and very dark hair your going to have high contrast which will show the diffrnece between tha hair transplant area and the native hairs .
I heard that in order to get good result you need to have low contrast between the skin and the hair. Thats why there alot of ppl that try to hide the thining by dye the hair blonde
