How many weeks is the most appropriate interval, and what is the duration of the laser hair removal effect?

I spend five minutes every morning on my way to work tidying up the growing hair, but I end up rushing and sometimes even bleeding. The fatigue on my skin is no joke. When I mentioned it to a colleague, they strongly recommended that I get laser hair removal sooner rather than going through the trouble every time.

I’ve really gotten interested because I heard that over time the marks fade away and the time spent getting ready in the morning is drastically reduced, improving the quality of life.

However, since I have to go after work or on weekends, I'm not sure how many sessions I usually need to get for the hair to stop growing back. For those of you who have tried laser hair removal, did you really feel less skin irritation and notice your skin becoming smoother compared to shaving? I think I need to hear from those with experience about what the ideal interval between treatments is.
