There are a lot of hair products that can help with frizz and fly-aways, especially during the summer months — but even with those products, it still all starts with the blow dryer. In fact, there are some blow dryers that are better for frizzy hair than others are, and those are the ones that are really the key to minimizing frizzy hair if that's something you're looking to do. A great hair dryer is able smooth hair and reduce frizz and fly-aways with minimal effort, even if it's rainforest-level humid out.
Unfortunately, you can't just pick one off the drugstore shelf and expect sleek, frizz-free results. I've been through countless hair dryers in my quest to find the best ones, and I've since realized that a few key technological features make all the difference.
For instance: Ionic technology is a must, because negative ions cause water molecules to divide into smaller particles and evaporate faster. A ceramic build is also important because it heats up much more evenly than other materials, which minimizes frizz and damage. Then there's infrared light or heat, which uses longer energy wavelengths capable of penetrating the hair shaft and drying it quickly from the inside out.
All of these blow dryers use one or more of these awesome features, and they've all got multiple heat settings and an ergonomic design, so you can get the most out of your dryer regardless of your hair type.
