American Mane

Did anyone try megasessions at American Mane or any other HT clinics? My bf had a consultation with AM staff and was told he needed 2 sessions, either 8-9 months apart but can get more grafts, or 2 days in a row but less grafts(5-6k grafts prob). My bf doesn't want to wait for several months for another procedure so I was thinking about a 2-day procedure. Any experience sharing and advice would be much appreciated.
