I do mine every so often, usually if I've got somewhere special to go. It's straight atm as I went to an Xmas do on Sat and am off to see Robbie Williams tonight (yay!). The last time I straightened was in August when I was on holiday in the UK and it was just easier to manage. I use a leave in called Vita 5 CPR then PM's seal and shine before blowdrying and straightening, then some MOP glisten drops when I'm finished. It seems to keep it's condition ok though I know when I straightened regularly it got pretty fried and eventually started snapping off. That's when I found nc.com!
