How do you usually schedule your laser hair removal treatments?

Managing my body hair has been a constant hassle, so I am planning to get proper laser hair removal this time. I’ve heard that rather than receiving this treatment just once, it is common to divide it into multiple sessions aligned with the hair growth cycle. I am wondering what the ideal schedule is for laser hair removal to see real changes. I’m not sure if many people get at least five sessions at 4 or 6-week intervals, or if it is better to take more time between treatments. Also, I would like to know approximately how many years the results last once the cycle is followed. I would appreciate it if those with experience could share their recommended schedules.
