Best hair dryer FAQs
What kind of wattage do I need?
Most experts recommend anywhere from 1800 to 2000 watts. More wattage means more power, so if you have thick hair, a higher wattage will cut down your dry time. "Lower only makes sense for those with fine, medium hair types that are straight," says Holdsworth. "Wavy and curly hair needs more power."
When traveling abroad, an adapter doesn't always work, and a blown outlet could damage your hair and dryer. Because compatibility varies to much country to country, your best bet would be to use the hair dryer in your hotel or, if it's somewhere you travel often, purchase a tool specifically for that destination.
What is the difference between ceramic and ionic technology?
Ceramic technology involves a constant flow of heat and is generally recommended for dry or damaged hair. "Ceramic technology distributes heat evenly through the tool, preventing hot spots that can damage hair," says Holdsworth. "This creates a consistent and controlled heat, which can help eliminate frizz and straighten hair without causing damage. Ceramic tools tend to work best on dry hair, as the heat can cause moisture from wet hair to evaporate and potentially damage hair."
Ionic technology emits negative ions that break down positive ions, producing static electricity in the hair. This neutralization process can help reduce frizz and flyaways, Holdsworth explains. "Ionic tools work by sending negative ions into the hair, making it more receptive to moisture, which can be especially helpful in humid climates," she adds.
While they serve different purposes, most hair dryers today offer both ceramic and ionic technology.
What attachments will I need?
Concentrator nozzle: Most hair dryers come with a concentrator nozzle, a thin, narrow attachment that helps to direct the airflow to a specific section of the hair. This helps to add volume, straighten the hair, and minimize frizz.
Diffuser: This wide, circular attachment evenly distributes heat to the hair without disturbing it, making it ideal for drying curls and waves, Hardges says. Because it's gentle on the hair, Coelho adds that diffusers can also benefit fine or damaged hair.
Brush: This attachment helps achieve smooth and shiny blowouts.
Comb: Similar to the brush attachment, the comb can help shape the hair and detangle.
Pik: This attachment, which looks like a comb with longer teeth, helps smooth and straighten curly textures while giving volume to the roots.
