Can Blow-Drying Your Hair Cause Split Ends?

Those who often use a blow dryer on their hair may not be able to imagine their locks without heat styling. While blow dryers can speed up the drying process and create the best looks, you've undoubtedly also heard that they can cause damage. According to a 2011 study published by the Annals of Dermatology, using heat above 203 degrees Fahrenheit can not only cause damage but also lighten the color of your hair. 

One of the largest concerns many have is split ends, which occur when the tips of your hair become extra dry and brittle. These can make your locks appear less healthy, which isn't ideal. Furthermore, once they've formed, the only way to completely get rid of them is with a haircut, though nourishing hair masks may slightly help their appearance. Therefore, the best way to treat them is by preventing them in the first place. Perhaps you're wondering if your blow dryer is causing split ends, and if so, here's how you can tell. 

There are mixed opinions about whether or not your blow dryer is causing your split ends. Some believe that no matter what preventative measures you take, you'll always see more brittle and less healthy hair when using any type of heat. Healthline, for example, recommends regularly taking breaks from heated products, as they can easily cause your hair to become dry. However, others like Philip Kingsley, say that using the device correctly shouldn't cause damage.

Therefore, one of the best ways to avoid dry tips is by properly using your hair dryer. If you use it on already dry hair or focus it on your tips, you're bound to see lots of damage. On the other hand, if you use the device on a lower setting and never keep it pointed towards one area for too long, you should see some great results while still maintaining your healthy mane. The higher the temperature, the more damaged your hair will be, so try to reduce the temperature whenever possible, as per the 2011 study published by the Annals of Dermatology. Therefore, keeping the blow dryer at a safe distance from your head is also essential, as heat that's too close to your strands may cause the ends to split.

Along with the above tips, using the right products is equally important. For instance, choose a blow dryer specifically created to protect your hair from damage. If you're looking for one of these devices, you could try out the popular Dyson Supersonic Hair Dryer, which claims to decrease flyaways and add shine. Those who have curls may even find the diffuser attachment that comes with it to be worth their while since it works to equally disperse the heat. In other words, it may further work to protect your hair. 

Another essential product you should use anytime you plan on adding heat to your hair is a heat protectant, which will coat the strands so that the heat doesn't cause as much harm. To apply, simply spray onto damp hair before using any type of heat styling device. Luckily, there are several heat protectants out there, including BondiBoost's Heat Protectant Spray, which is vegan and great for colored care, and the Protect & Prevent Spray by MoroccanOil, which feels lightweight and repairs hair.
