The system is used through that tape and glue.Since this system uses glue and tape, it is also called multi-glue system. This system is very useful for hair patches because it saves hair patch  base. In this method, hair patches can be kept on the head for 4 to 6 weeks but it  depends on the weather. If the weather is cold it will last longer And there are no side effects at all.
