Summarize the following:
The ion technology behind these hair dryers allows them to dry your hair much faster with the least amount of damage. The negative ions the dryer emits cause your hair cuticle to lay flat, which smooths out frizz and coarseness, resulting in straighter, shinier hair.  Ionic blow dryers tend to be on the pricy side, but there are affordable versions out there. Be sure to get one that comes with a nozzle attachment. Look for one that is at least 1500 watts. Ceramic-plated flat irons straighten hair faster and more efficiently than other types of irons, and they are also the most gentle on hair. Look for one that's no wider than an inch and a half, since anything wider isn't ideal for straightening hair (the wider ones are better for styling hair).  Ceramic flat irons are the best choice for those who have fine to normal hair. If you have thick, curly hair, opt for a gold or titanium-plated flat iron.  Some companies make flat irons plated with a blend of ceramic and titanium – these are excellent choices for coarse hair. For general hair brushing (not blow drying), a boar bristle brush is the ideal choice because it's very gentle on your hair. Boar bristles also add shine and sleekness by redistributing the natural oil in your hair as you brush through it. Avoid hair brushes with nylon or plastic bristles for general hair brushing. These tend to cause breakage and hair damage. These are the ideal brushes to use on your hair when you're in the process of  blow drying it. Make sure you get one that has a combination of boar hair and nylon bristles, which will create a smooth, glossy sheen. Avoid using round metal brushes when drying your hair to prevent breakage and damage.

Summary:
Invest in an ionic blow dryer. Get a high-quality ceramic flat iron. Buy a hair brush with boar hair bristles. Get a flat paddle hair brush.
