What is the cost of a hair system?

What is the cost of buying and maintaining one? And also how does it work, does anyone here have any kind of experience with it?

Good hair systems over a 5 year period will cost you more than a hair transplant. You have to have more than one and they wear out every year or two.  You have to wash them often, wash your hair and remove the glues, change them as you have hair cuts, etc.  I wrote this back in 2011: https://baldingblog.com/repost-my-hair-system-cost-me-over-16000-in-5-years/
