Does a Person's Skin Color Affect the Noticeability of hair transplant Scars?

Yes, generally speaking the best results are when there is the least amount of colour contrast between the hair and the skinIn other words, the most demanding hair transplant is likely to be in pale white skin and very dark coarse hair

Excellent question if skin and hair color have significant impact on the results of hair tranplant.  If there is low color contrast, such as blonde hair with light skin or dark hair with dark skin, that is low color contrast and enhances the result and makes it more natural.  If the opposite...high color contrast...black hair on light skin or light hair on dark skin, the surgeon must be very careful with technique to keep grafts natural.
