The hair bonding procedure is a non-surgical method of replacing your hair in which a thin layer of new hair is attached to your existing hair with an adhesive. As this method uses medical-grade glue, it does not irritate the scalp, and either natural or synthetic hair may be used. It blends in naturally with the original hair, giving it the appearance of shiny hair. It is important to know that ancient Egyptians used sheep fur to create hair extensions, a practice most people are not aware of. Even though we are not aware of the evolution of non-surgical hair replacement techniques over the centuries, it is fascinating to observe how they evolved.
