grey scales

for the past few months my BP has had these little grey colored scales on her. they almost seem to be stuck shed on individual scales. At first it was just a few scales (these are on her back not belly) then she shed and they appeared to have gone, a few weeks latter some of the scales began to dull back to a greyish silver. This started to happened when i had a certain hide spot in the enclosure so i took it out and put in a diffrent one, after she sheds again i will check to see if they are gone. just hoping someone knows if this is harmful for her and what to do if it is.

Is she getting old?

It could be a number of things. Stuck shed or a scratched scale (the outer layer of skin gets scratched off making it look dull) are the most likely.

Unless it looks infected then I wouldn't worry about it. It happens from time to time.

she isnt old, i got her a 1 1/2 years ago and she was a baby then.
