Does the cost of laser hair removal vary significantly depending on the area?

I get really stressed every summer because my skin becomes sensitive due to shaving. My neck, in particular, gets red and stings after shaving, so I'm considering getting proper laser hair removal this time. However, I noticed that prices vary quite a bit depending on the area, so I'm curious about the process. I'd like to know which areas are usually the most expensive for laser hair removal, and how many sessions are needed to achieve a clean finish. I've heard that satisfaction is high once you start laser hair removal, so I'm wondering if people with sensitive skin can still get it done without significant irritation. I feel like just searching on my own has only made me more worried, so I'm thinking about getting a consultation.
