Ooooh, cutting so much hair off is an odd experience! A few years ago I used to have SUPER long hair (I could almost sit on it), and I finally decided that I'd had enough of it being slammed in the car door, caught in the seat belt, pulled by the chairs at school, and caught in various other objects. It was hard to take care of it constantly, not to mention I could go through a family-sized bottle of shampoo in the time it took for someone with medium-ish hair to use a regular one.
It was so weird cutting it off... my head felt lighter, I could wear it in a ponytail without getting a headache, and it was just considerably less hair than what I'd had for 3 years.
Hoping you feel the same relief!
