Premature Hair Graying Linked to Smoking and Obesity Interview with:
Seong Jin Jo, MD, PhD
Department of Dermatology
Seoul National University College of Medicine
Seoul Korea.

Medical Research: What is the background for this study? What are the main findings?

Response: Hair graying is a natural aging process, but some people develop hair graying in their youth.

In this study of young Korean males, we found that obesity, smoking, and family history were significantly associated with premature hair graying.

Medical Research: What should clinicians and patients take away from your report?

Response: Our findings would offer a possible approach to health education against obesity and smoking, particularly in young people.

They may also suggest clues of natural aging process to researchers.

Medical Research: What recommendations do you have for future research as a result of this study?

Response: Large-scale studies in females and other ethnicities would be a valuable addition to the evidence base.

Further researches in the association between hair graying and systemic disease or life expectancy might show interesting results.
