CT Scans and Hair Loss

(female)
Dr. Rassman, thank you for time. I have read your answer as well as several other sites that state ‘A’ CT scan is not sufficient to cause hair loss. I have been having repeated intensive CT scans. My research has shown that the amount per CT scan (chest, abdomen and pelvis) is relative to approximately 1/4 the radiation exposure of a survivor of the atomic bombs that were set off in Japan. I have now had 8 such scans in a year and a half period. There are more issues than hair loss that drove me to my doctors seeking answers, but they have none for me. The only other significant health or living circumstance change for me in this time period has been weight loss. I ask you again because my question is so specific to the amount of radiation I am receiving… Is it possible repeated CT scans (versus ‘a’) could cause hair loss?

Certainly it is possible that radiation from multiple computed tomography (CT) scans of the scalp could produce hair loss. Various CT scanners produce varying amounts of radiation but even your 6 CT scans to the head may not be enough radiation to produce hair loss like victims of the atomic bomb experienced. There is not much information available to produce a more certain answer to your question.
