How many laser hair removal sessions are recommended for clear skin?

As the weather gets warmer, the smooth hair growing on my arms and calves is starting to become much more noticeable. I have always used hair removal cream or shaved, but my skin keeps getting red and developing issues like folliculitis, so I am thinking of getting laser hair removal treatment that destroys the hair roots for a smooth finish.

I really want to receive treatment using the latest air-strike equipment that does not directly touch the skin. I have heard that multiple sessions at regular intervals, aligned with the hair growth cycle, are necessary to ensure hair does not grow back cleanly. I would like to know how many sessions are typically recommended as a standard to achieve satisfactory permanent hair removal results.

It would be very helpful for me to schedule my appointments if you could provide a specific guide on laser hair removal, such as whether about 5 sessions are sufficient, or if I need to extend the care to 10 or more sessions if my hair is thick.
