Hey Regina,
I don't think the statement's true for various reasons generally
related to molecular structure of fur and hair, and it doesn't
logically make sense from biological perspective. (But I might be
wrong!) It may be distantly related to the myth that polar bear's fur
acts as a UV light guide to warm the animal. Please see: http://it.stlawu.edu/~koon/polar.html
for various references and a brief discussion. It includes a
reference to the reflectance and absorbance of arctic homeotherms
which ought to have what you need.
All the best,
Charlie
