Walk the hot tools aisle of any beauty supply store and your head is bound to start spinning. The options are pretty endless and confusing. Ionic, tourmaline, nano, and the features go on. Whether your hair is fine, textured, color treated or super long, you want a dryer that's going to essentially remove only the excess moisture, in the shortest amount of time.
Depending on the time it typically takes to dry your hair, you may want to consider how light or heavy the device is and the end goal. Not everyone wants a supersleek blowout. For curls, volume is key, and if you're color treated, you probably don't want to go to the highest heat setting.
Hairstylist Stacey Ciceron says that it is more important to know how to work the settings on your dryer and to choose one based on how it feels to you and your comfort level. A higher wattage means that the airflow is faster, which ultimately will dry your hair quicker.
As for the attachments, Ciceron broke down what each is best for: Use the concentrator nozzle for blowouts and when taking hair from curly to straight. The diffuser attachment is good if you're trying to dry coily, curly, or wavy hair. And use the comb/pick to stretch out and dry textured hair.
There are so many factors to keep in mind, but if you want to know flat out which one to buy, here's a little guidance that will hopefully make selecting the best blower for your mane less of a headache.
