Styling your hair with a hair dryer requires three main things; heat, tension and direction. You need to apply heat to the hair, while positioning your hair with both a brush, and the dryer's air flow to create the shape. To harness these techniques without damaging your hair, you need a hair dryer with enough power and heat, but not so much that it causes breakages. It is a balancing act for sure.
Hair dryers range from as little as $20 all the way up to the $700-$800 mark, but it can be difficult to figure out which devices are actually worth the higher price tag. When you're looking to buy a hair dryer there are three main specs to consider; wattage, max temperature, and hair protection features.
Wattage
The higher the wattage, the more power the hair dryer has which means it can dry your hair faster. The downside to high wattage however means that the power and heat from the hair dryer can cause more damage to your hair if it isn't harnessed properly. For dryers with more than 1600W, check the air flow directionality and make sure it blows concentrated, and straight on.
Maximum air temperature
We all know that heat can damage hair, but it actually happens earlier than you may think. Any heat above 60 degrees C can cause some level of hair damage, and above 140 degrees C can cause structural and irreversible damage. Hair even starts to melt at 220 degrees C. Look for hair dryers with lower maximum temperatures (like the Dyson Nural) to prolong the health of your hair.
Hair protection features
Nothing will ruin a gorgeous, bouncy blowout like dull and lifeless hair. Hair dryers with ionic and ceramic heating elements add an additional layer of protection between the heat and the hair, which helps to minimise hair damage. Ionic charges also help to tame flyaways and static, leaving you with smoother and shinier locks.
