A hair transplant cannot cause cancer. There is no evidence or direct link between hair transplant and any type of cancer.
Cancer is the growth of abnormal cells that may or may not gradually spread to other parts of the body. Several reasons and factors can lead to cancer. However, the primary reason behind this myth is that most organ transplants lead to cancers. However, this is also precisely the reason that proves it otherwise.
Organ transplants can cause cancer. However, hair is not an organ. Although a part of the body, our hair is made up of a tough protein called keratin. The keratin helps protect your hair and scalp from harmful substances.
Since hair is not an organ, it cannot cause cancer.
