have you tried calling the files ".jpg" instead of ".jpeg"? just one thought.. anyway... here is what I've learned about Grey's hair.. first of all.. if you're going to work on it make sure that you DON'T have the checkbox checked where you apply one texture to the whole object since different materials are mapped with different files... also by default the hair is scaled to 103% in X, Y, & Z... I scaled them back down to 100% each.. Hmm.. I did go through and make sure that the min and max transparency were both set to 100% too... (for each of the materials on the hair object)... hope that helps!
