How Often Should I Change My Hair Dryer?

Hair dryers usually maintain good performance for 3 to 5 years. 
The specific life of a hair dryer depends on a number of factors, including frequency of use, maintenance, and quality. High-quality hair dryers usually have a longer service life. Proper use and proper maintenance can extend the life of the hair dryer. It is recommended to clean and check the hair dryer regularly to keep it in good condition. If used often or not properly maintained, the life of the hair dryer may be shortened.
