I love your videos, waterlily!
Well, this was my hair in Dec 2010:
and now it's as long as it is. I only cut my ends every 2-4 months, and not too much at a time. I don't have the best ends, but I feel like I never do, even when I had shorter hair & regular trims.
I wouldn't give up my long hair even though it has many cons. I feel like I look bad with shorter hair ;(. I DREAD SHOWERS. Detangling takes forever, and I shed so much. I wash my hair 1x a week so that's why it's probably so bad. But I honestly don't have the time/patience to do more. I need to do more masks or something, because my hair doesn't have a lot of shine. It never really did though.
