I'm thinking of getting laser hair removal. How many sessions do I need?

If you trim it with a razor, it looks neat for now, but
It came back up quickly after just a few days.

Especially in the summer, since I often wear short sleeves or shorts
There have been more days that bother me.

I've also thought about waxing.
The cost and maintenance are a bit of a burden to receive it regularly.

Then I heard that many people around me were getting laser hair removal.

It’s not a one-time thing, but
I've heard a lot of people say that it becomes easier to manage in the long run.

So, I am thinking of starting laser hair removal this time as well.

However, now that I've actually looked into it, the explanations vary slightly from hospital to hospital, so it's confusing.

Some places say that it is effective after just a few sessions.
I heard that in some places, you have to get it done quite a few times.

I know there are individual differences, but
I am curious to know how good it was for those who actually received it.

Rather than the hair disappearing completely
My goal is to reduce it enough so that I don't have to shave often.

If you consistently receive laser hair removal
I'm also wondering if the hair growth rate slows down.

I would like to know if there is also an effect of making the hair thinner over time.

And I also saw reviews saying it's more painful than expected.
I am also curious about the actual extent of it.

Whether it is tolerable
Or please let me know if there is a significant difference depending on the area.

My skin is sensitive, so I am worried about redness or stinging after the procedure.

By any chance after getting laser hair removal
Are there any of you who have had a skin breakdown?

Conversely, I wonder if there are people who found it less stimulating than expected.

The advantage I look forward to the most is, of course, that it becomes easier to manage.

If the need to shave every time is reduced
I think the satisfaction level would be quite high just with that.

Those who have actually received laser hair removal
I also wonder if the frequency of shaving has definitely decreased.

And whether it grows a lot again even if you take a break for a few months in between
I also want to know how much maintenance is required.

The cost is also quite steep when you consider it per session, so
I'm also wondering if it's okay to pay for multiple episodes from the start.
