I bought an ISO iron back in October and one of the "selling" points they used was that I could use it on my wet hair. The woman was telling me that doing so would help seal in the moisture. Of course this is as my hair was steaming away from the little bit of water she spritzed me with. Anyway, I have seriously frizzy hair and I've been cheating since October. I wash my hair every other day and most often let it air dry, except for the bangs. I use the flat iron on them and now I know why my hair has been breaking and has so many split ends in the front. I used to use a hairdryer and round vented metal brush. Apparently that's bad but my hair does not flatten well at all, ever. I've found that even with the hairdryer, I have to be extremely careful of the heat on my scalp. I noticed that my hair was thinning and when I stopped with the hairdryer, it got better. I guess I traded one bad for another though.
