What is hair bonding? Can it give a natural look?
Any treatment available to people over 60 years of age, with long standing baldness?
You may be taking this term out of context. Glues that are used to attach hair systems (wigs) are said to be bonded to the scalp. These can cause damage to weak hair, leading to further loss. They may look natural, but they also could take a lot of work and money to maintain that natural appearance.
Hair loss treatments that I recommend include transplantation and medication. Your options depend on a variety of factors, but since I have no info about you (aside from age) I couldn’t begin to list what those options might be. But yes, generally there are treatments available even at 60 years old.
