Susan Walsh
Primary Investigator
Brief description of study
The purpose of this study is to research on the genes that cause different hair colors in an individual using the genetic information extracted from the hair samples the study participants provide.
Detailed description of study
The purpose of this study is to investigate why there are differences in hair color between scalp and beard hair by studying genetic material and pigment measures obtained from the hair follicle/bulb samples collected from the participants.
