Laser Brazilian Before And After Questions About Brazilian Laser Hair Removal?

Questions about Brazilian laser hair removal? - laser brazilian before and after

I asked about this a few days ago, but I have more questions:
I mixed information online. After its initial meeting, I understand that hair grows a little more, but is in reality. How long does it take? I've heard that you can shave again after four days and help you out.
How many sessions are necessary to get all the hair? (Preferably by a person with fair skin and dark hair because it makes a difference, answered).
I understand bow that has all his hair. Is it so humiliating that I (on hands and knees to imagine).

What do you think was the worst part of the experience? The best?

Thank you for your help!
