This is the dyson blow dryer and it dries hair fast for shiny hair. It has faster drying time than other hair dryer which is healthier for your hair. It would be less heat and less time spent on drying your hair. It is good to use a dryer that gets the job done fast. The only thing I don’t like about it is the price, which is $490.00, I think the price is outrageous for just a blow dryer. But would you ever pay this much for a Hair dryer?
