How many sessions is recommended for laser hair removal? How many times do you usually get it done?

It’s a hassle to shave every time, and it feels like my skin is getting damaged, so I’m thinking about taking this opportunity to start laser hair removal.

I've heard that the time it takes to see results varies from person to person and from body part to body part. Clinic packages usually come in units of 5 sessions, but I'm curious how many laser hair removal sessions are needed for areas like underarms or the upper lip to reach a level where hair barely grows back. Is 5 sessions sufficient to see results, or should I plan for 10 or more sessions and sign up for a long-term package?

Although I understand that the recommended number of sessions varies depending on hair thickness and density, I am curious to hear reviews from those who have already received it regarding at which session you typically start to feel like the hair really stops growing. Also, by any chance, what is the optimal interval for laser hair removal for the best results?
