How many sessions is recommended for underarm laser hair removal?

I am considering getting laser hair removal this summer to reduce the hassle of shaving. I have been managing my hair with a razor until now, but it grows back quickly after just a few days, and since my skin is sensitive, it often stings or turns red after shaving, so it is stressing me out.

So, I’m looking into laser hair removal because I want to take proper care of it this time, but I’ve noticed that the recommended number of sessions varies slightly from clinic to clinic. Some places say about 5 sessions are sufficient, while others say you need at least 10 sessions to be satisfied, so I’m confused about what criteria to use.

For those who have actually received underarm laser hair removal, how many sessions did you need to notice a significant reduction in hair? I am curious whether you were satisfied with just 5 sessions, or if additional treatments were absolutely necessary.

I would also like to know the recommended treatment interval (every few weeks), the level of pain involved, and whether the hair tends to regrow significantly over time. Please share any experiences you have had regarding whether even those with sensitive skin were able to undergo the procedure without significant irritation.

I think honest reviews from those who have actually received the treatment would be the most helpful, rather than advertisements. I would appreciate your advice regarding the recommended number of sessions and satisfaction levels for underarm laser hair removal.
