Before purchasing a blow dryer, you must consider three things. Here are the factors:
Nozzle Size. It is better to avoid short wide nozzles. Mainly because it can change the airflow from the blow dryer. Furthermore, it is difficult to find the change in a broken part.
Cord Length. Choose a longer cord length because it will be easy to maneuver.
Wattage. Choose a blow dryer with a wattage less than 1900—the high the heat, the limited the move you can make. In addition, a higher wattage might not suit your electricity power at your house.
