San, I got may hair cut a couple of days ago, and played around with my flat iron before that. I get tired of being curly/wavy all of the time...but it's easy. I talked about it with my stylist, and she confirmed what I figured out. I was using lower heat in an effort not to cook my hair. It works better when it's on the hottest setting, and I move it through quickly. I also use a product to help relax my curl. Don't know if Taylor or Renata have any other tips. :o)
