Regret having Laser Hair Removal after 1 session: Will my hair grow back?

After 1 brazilian Laser hair removal (LHR) treatment I decided that I wanted to keep some hair.  Only "after" the LHR session I panicked and have been feeling very uncomfortable since then with my choice to have a brazilian. So I want to know if it is possible to have a traditional bikini LHR.  Specifically, I want to know if my hair will grow back (even though it has ALL shedded) if do not continue LHR treatment on the mound/labia area. Also, I want to know if the new thin hairs that grow - if they grow back at all - will thicken if I shave often. At the moment I have no hair and the skin is smooth, but it's been only 3 weeks since my first and only LHR treatment.
