Which procedure is considered a type of surgical hair restoration?

Knotting, also known as hair weaving or hair bonding, is a method where hair is attached to existing hair using a knotting technique or adhesives. This process can provide a fuller appearance of hair but does not involve any surgical techniques.

On the other hand, surgical hair restoration typically refers to methods such as follicular unit transplantation (FUT) or follicular unit extraction (FUE), where hair follicles are surgically removed and reimplanted in areas where hair is thinning or balding. Surgical procedures change the actual structure and state of the scalp and hair roots.

In the context of the question, the focus is on types of procedures that include direct surgical intervention to restore hair, and knotting does not fall into this category. Hence, it does not qualify as a surgical hair restoration method.

While implanting hair fibers may seem similar, it is also a non-surgical method. Scalp micropigmentation is a cosmetic tattoo technique, and laser therapy is non-invasive. Therefore, a key understanding in this context is the distinction between cosmetic enhancements and actual surgical restoration methods of hair.
