Dr. Lawrence Gibson likens bad health information on the Internet to food poisoning.
Consumers, he says, need to be aware and will find reliable information at MayoClinic.com.
Dr. Gibson, a Covington, Ky., native, has been with Mayo Clinic since 1986 and is board certified in dermatology, dermatopathology and immunodermatology. He is a professor of dermatology at Mayo Medical School and a consultant in the Department of Dermatology.
Dr. Gibson has served as the fellowship director for dermatopathology and as chair of the Laboratory Division in the Department of Dermatology. He is especially interested in inflammatory disorders of the skin, including vasculitis, and in lymphoma affecting the skin.
"Electronic information has become a staple in the diet of a health conscious society," he says. "It's important to avoid misinformation and provide a credible source for health information. Using this analogy, it's critical to avoid 'indigestion' or, worse yet, 'food poisoning' by the ingestion of tainted information."

Question
Shaving hair: Does shaved hair grow back thicker?
Is it true that shaving unwanted body hair makes it grow back thicker and darker?
Answer
from Lawrence E. Gibson, M.D.
No — shaving hair doesn't change its thickness, color or rate of growth.
Shaving facial or body hair gives the hair a blunt tip. The tip might feel coarse or "stubbly" for a time as it grows out. During this phase, the hair might be more noticeable and perhaps appear darker or thicker — but it's not.
Consult your doctor if you notice a sudden increase in facial or body hair. This could be a medication side effect or a sign of an underlying medical condition.
