Regret After 1 LHR: How Long Until I Know How Much Hair I Have Been Left with?

I regretted having had a brazilian with laser. Only had one session (white skin, dark hair - Soprano machine). It's been 8 weeks. I am barely seeing hairs. At the moment very few, sparse hairs but they are thin; also small patches with smooth skin. Can hair grow from those patches? I have read that pubic hair has a 6 month cycle, so in 6 months time will I have a real "picture" of the amount of hairs I have been left with? Is a "bush" still possible ? hair density ? hair length?
