If I miss a laser hair removal cycle, do I have to start over from the beginning?

Hello. I am currently undergoing laser hair removal, but I have a question because it seems difficult to schedule my next appointment due to personal commitments. The clinic advised that it is important to receive laser hair removal at regular intervals, so I would like to know if the effectiveness will significantly decrease if I postpone my appointment by about 1 to 2 weeks.

I have only had about three sessions so far, so I am worried that if I wait too long, the effects of the laser hair removal I have received so far might diminish. I see conflicting opinions online; some say it is fine as long as it isn't too late, while others say sticking to the schedule is the most effective. I would like to hear from those who have actually experienced this.

I am also curious if the laser hair removal cycle varies by body part. Since hair grows at different rates in areas like the underarms, legs, and upper lip, I would like to know if it is appropriate to receive treatments on the same day, or if some people schedule separate appointments for each area.

If anyone has missed an appointment, I would appreciate it if you could share how you proceeded afterward and what guidance you received from the clinic. I have many questions as this is my first time getting laser hair removal.
