Misikko gifted me this pink ceramic flat iron and is something I'm definitely going to be using daily. My hair is naturally wavy and though I prefer it that way on most days, it's nice to change it up and wear it straight once in awhile. Check out the difference:
Even if you want tousled curls, I think starting with a straight base gives your hair a more polished effect. I've been so accustomed to using an old school gold Helen of Troy 1.5 inch barrel curling iron. I can't seem to part with it though I will give it a whirl with the flat iron one of these days. I hear it works just as well!
After, I use hairspray to keep the curls in tact keeping it nice and light without weighing it down. Bedhead's Hard Head is the hairspray of my choice but a lot of people do like Big Sexy Hair as well. You can add a shine spray or gloss after- I like Abba Pure Shine Spray- it smells so good.
