The best hair dryer is a concept that cannot really be defined. Why? Simple. What works for some people will not work for everyone else. From this point of view, pay special attention to your hair type when about to purchase a hair dryer. Those with long and straight hair might want to consider a ion based function, which dries the hair way faster than normally. On the other hand, wavy or curly hair can be dried with fine movements all across the hair – from top to bottom. These things might look irrelevant, but they will keep your hair healthy.
