Here are a few factors to consider:
1. My hair is naturally straight. If you have curly hair, you can follow the same method, it just might take you a little longer.
2. I have a high quality flat iron (GHD 1 inch), that can be purchased through salon's or online.
3. If you have longer or shorter hair than me, you might get a different finished look, but you can still use the same method I use!
See this post to learn what products I use daily (and what I used for this style).

If you don't have a GHD Flat Iron, still give this a try! If you aren't able to get it as smooth, or straight, you may need to add a smoothing product, like this one, or invest in a better flat iron.
