Me, too. I never have any special instructions...except no barrets or hair pins. Nothing metal...and no bra with an underwire in it (I learned that the hard way...).

The only test I had to have done where I had to have clean dry hair and no lotions, makeup or other substances on my skin was the one where they glue those electrodes on your head and other parts of your body (arms, legs, etc.). I cannot remember what the test was....I just remember all the gunk left in my hair. But MRI's are easy for me....just gotta remember the bra.....
