If goopy products and a blow-drying don't seem to do the trick, a flat iron would be the next step. When you're shopping for a flat iron, keep these attributes in mind:
- Plate material: You can get cheap flat irons with metal or glass plates, but they create uneven heat. Spend a little extra for ceramic, titanium or tourmaline.
- Width: If you have short or fairly straight hair, get a thinner plate -- maybe an inch or so. If you're working with long, thick or really curly hair, go for at least 2 inches.
- Adjustable heat settings: If your hair isn't totally curly, you can use less heat than someone who's dealing with tons of frizz.
