I've just done if chop due to stringy limp curls (and I had no clue what I was doing with long hair!).

I've had it cut to just below my chin so I can tie it back if needed. It feels so much healthier, easy to curl (I don't even need gel), really soft and no tangles. Its also nowhere near as dry. However! - I am still getting used to the look, I think it's just so different.

Also, I don't know about other people's hair but mine goes into shock after its cut and can take a week or 2 to settle down...

Good luck!
