1. A method for improving visualization of hair for use in hair transplantation, the method comprising:
- illuminating with a light source a skin surface having blood on a portion of the skin surface;
acquiring an image of the skin surface, including the portion of the skin surface with the blood thereon, while the skin surface is illuminated with the light source;
adjusting a wavelength of the light source such that contrast between the image of the skin surface without blood and an image of the blood is minimized; and
using the adjusted wavelength of the light source to visualize or improve visualization of a hair graft located in a region of the skin surface having blood thereon.

Abstract
A system and method is provided for improving the visibility of hair on the skin surface, in a region that is bloodied or bruised, and potentially expanding the candidate pool of the hair grafts to be selected for harvesting. The system uses a light source comprising at least two emitters and the method comprises controlling the contrast between the image of the blood and the image of the skin surface. The method of the present invention may be implemented with various hair harvesting and transplantation systems, including manual, partially automated and fully automated systems.
