Does the hair that falls out after each laser hair removal treatment stay gone?

I started getting laser hair removal and noticed around a week after each treatment if I gently pull on the hair it just comes out. If I don't pull on it, it still comes out eventually. A lot of hair seems to fall out after each treatment. I'm wondering does the hair that fall out stay gone, or does most of it come back by the next treatment? Because I feel like I am pretty hairless around 1.5-2weeks after treatment, but closer to treatment time again I can see more hair growing in.
