OMG.....i thought you were going to say your hair is falling out!!!! That's my second biggest worry about the CD..............after my worry about my teeth falling out.
send them back to GHD they will send you a new pair if its a fault.
I have read it somewhere that someones teeth fell out after finishing their SS time but they had done it for much longer than the recommended time. I am obsessed with cleaning my teeth and gums now
