Hello Dr – I read with interest your answer about MRI scans and how there is no link from them to hairloss as they use magnets. What then, would be your opinion on CT Scans? Could these cause hairloss and if so over what time period? i.e – a few days after the scan or a few years? Thank you for your time.
The amount of radiation that a CT scan (also known as a CAT scan) will administer is not sufficient to cause hair loss. It takes much, much more radiation to cause radiation sickness and have the side effects to cause hair loss.
