PETER HALPERIN, MD: Right. It's actually removing some hairs and examining those under the microscope and examining the scalp for redness or inflammation and removing some of that material by biopsy or by some type of blade removal to examine it to ascertain why the patient is losing the hair.
DAVID FOLK THOMAS: Of course, I was thinking the Three Stooges were getting hair pull tests all the time.
PETER HALPERIN, MD: There's a whole range of things that we go into with a patient when they have hair loss.
DAVID FOLK THOMAS: Shari, add to that and tie in the diet part.
SHARI LIEBERMAN, PhD: It's interesting that you mention the hair pull test, because there are some very specific nutritional deficiencies, and the classic symptoms of these deficiencies include hair loss. Also, I didn't know that there was actually a hair pull test, but you can actually pull the hair out easier than it would normally pull. You can do it with very, very little difficulty. There are some nutrients like essential fatty acids that play a role in skin, hair and nails and other things as well. These essential fatty acids, like omega-3 fatty acids, are not the type of fatty acids that people are eating a lot of, because the sources of them basically include fish, like salmon and mackerel (not everybody eats that) or flax seed. When was the last time you had flax seed, David?
DAVID FOLK THOMAS: If I could tell you want it was, I could tell you.
