I've been transitioning since August 2007. Last time I flat-ironed was a few weeks ago because I had to renew my license and I didn't want to wear a bun (license came out great and it was windy as heck that day!) I don't plan on using heat for a while, I just wash/condtion, air dry, use moisturizer, maybe some gel and wear a puff. It's working for me, my hair is at APL when straight.
