Why is there such a big price difference for laser hair removal?

I was looking into laser hair removal and was shocked by the prices lol. Even though it's the same laser hair removal, the price difference between clinics is quite significant!!

At first, I didn't know why, but after looking into it, I heard that the difference depends on the equipment used and the number of sessions :) Still, the difference is bigger than I expected, so I'm having a hard time deciding where to choose ㅠㅠ

When I look at laser hair removal reviews, I'm confused because some people say they were satisfied because they started with a really cheap promotion, while others say it ended up being more expensive than expected due to additional costs lol.

Especially since laser hair removal often requires multiple sessions, I think the total cost is also important!! I realized that if you decide based only on the initial price, it might become a burden later on.

Still, I'm envious when I see people who are highly satisfied with laser hair removal talking about how the stress of shaving has disappeared haha. I think reducing my preparation time every morning is also a pretty big advantage!!

If anyone has had laser hair removal, I'm curious to know how much it cost :) Please also share any experiences where it was cost-effective~
