Currently, I am 6 wks post. I am shotting for 12 wks right now, but I access the NG to see how much it is and can I handle that much every 2 weeks. So far I have about 1 inch NG. Which is definitely not enough for me to want to get a retouch. I think I need at least 2 inches for a retouch. But my ultimate goal is every 6 months. I am working up to it.
