First of all, the hair transplant operation is the operation on the scalp surface, and the local anesthetic is only injected into the subcortical layer. The human scalp can be divided into five layers: cortical layer, subcutaneous layer, hat-shaped aponeurosis layer, aponeurosis layer and periosteum layer. The brain and nervous system of the human body are in the skull, and the skull is wrapped with periosteum and aponeurosis, so the brain and nerves will not be hurt during anesthesia.

Of course, going to a regular hair transplant hospital is an important prerequisite. Regular doctor with rich experience in hair transplant. Don't ignore this prerequisite. If you blindly choose an unqualified hair transplant hospital, it is really hard to say what the consequences will be.

The development of hair transplant technology has been very mature so far, and countless patients have rebuilt their self-confidence through hair transplant surgery. It would be a pity if friends miss hair transplant because of some stereotypes.
