HOT TOOLS SIGNATURE SERIES EMEA 1875W TURBO IONIC HTDR5577, Hair dryer with ionizer

Why ionization in a hair dryer?
Under the influence of the warm air used to dry the hair, positive charges develop on the surface. The result is static hair. Positive charges are responsible for the hair not looking good, but also cause problems when trying to style it. The solution is an ionizing hair dryer. The hair dryer emits negative charges that neutralize the positive charges on the hair. Hair is static, smoother, easy to manage.
What is a diffuser useful for?
The diffuser in dryers is a plastic cover with long projections. This unobtrusive device will be irreplaceable every time you want to style your hair. With a little practice, you'll be able to quickly change your image with a distraction. The diffuser is suitable for both natural curly and permed hair. Also, if you have fairly straight hair, you can use a curling iron in a curling dryer. In that case, however, you will have to use a little more setting foam to style your hair.
What is the concentrator useful for? 
A hair dryer concentrator that has a narrow gap through which the air comes out not only greatly increases the air flow, which speeds up hair drying, but will also be useful when you want to direct the air to one selected place. A concentrator, like a diffuser, will also be useful for styling your hair, especially if you want to straighten your hair. One thing is for sure, with a concentrator you can be absolutely sure that your hair will be thoroughly dried after washing.
