Hiya LH~
It is the same trim she and I are referring to on our sites. I really thought it was around 4 inches I trimmed, but she did tell me that it was more like 6 inches. We didn't video it, or photograph it either.
I was honored that she trusted me enough to do this for her, she hadn't had a trim in a really long time & was pretty nervous to take off so much, IMO. Something only a fellow LongHair could empathize with 
. We hate to do it...but it is a part of the maintenance. 
If you've seen her latest videos, you'll notice how full and blunt her hair is now. More Beautiful than ever!! 
Kiss
Leona
