Recommended to remove hair extension microrings for an MRI scan

[Siansy]

Hi guys, one of my clients I fitted her new hair extensions with microrings last night has been told today she needs a MRI tommorow. I'm not 100% sure what metal they are not believe to be copper. I buy in bulk mainly. I kniw neither copper or aluminium are known as magnetic. But MRI s are so strong in recommending to take out. Poor clients I've only just removed some for another client for a MRI yesterday. Thankyou in advance x
