Hair transplantation is a kind of micro-plastic surgery, a typical minimally invasive operation, and the operation is not dangerous. Why dare you say that hair transplant is not dangerous? This is because in the process of seamless hair transplantation, all high-precision instruments are used, and the operating range is only on the scalp surface, which will not harm the blood vessels and nerves of the human body. Generally speaking, hair transplant surgery is a "skin injury" and there is no danger.
