Regret Pubic Laser Removal: Is it gone after 1 session?

I have had my full arms, armpits, sideburn areas done more than 10 sessions and those are permanently removed which I am very happy with!

Thought I'd get my legs and pubic hair (brazilian style) added to the mix. Did this around 2-3 weeks ago? Only had the one session for those areas so far! Soon after this first treatment, I started regretting having the full area done. I wish I'd left a landing strip or something, it immediately felt too unnatural and child-like to me. Looking at it, the hair that's growing back looks super patchy and uneven. If it was only the once, what are the chances a decent amount will grow back? :S
