I am curious about the number of laser hair removal sessions required for the arms.

Lately, I've been really bothered by my arm hair, so I'm considering getting laser hair removal. I tried shaving it off with a razor once or twice, but it felt like it was irritating my skin and making the hair darker, so I'm hesitant. I'm wondering if I need a lot of sessions. I'd like to know the typical recommended number of sessions for arm laser hair removal. I've heard that it varies depending on individual hair thickness, amount, and skin type, but I'd like to know how many treatments are generally required to achieve a perfectly clean and smooth finish.

Also, regarding the treatment cycle, I would like to know what the optimal interval is for maximum effectiveness and how much arm hair can be reduced after about 5 sessions. Arm hair seems to be on the thinner side compared to other areas, so I am curious to hear reviews from people who have actually tried it and whether the laser works well even on thin hair!
