It sounds like they mean the same thing. But there is a difference!

While hair dryers used at home dry hair by blowing only hot air, blow dryers have a body designed to style hair while drying it. Hair dryers have wide nozzles and a low motor speed.

According to fluid mechanics, air volume is equal to the product of air speed and the cross-section through which the air flows. Because the air outlet in blow dryers is narrow, the air velocity increases. The faster air forces out the very hot air generated by the powerful resistor inside, making hair styling easier.

Blow dryers differ from hair dryers in terms of both the motor speed and the resistance required to generate higher heat. Blow dryers differ from hair dryers in terms of their power and heat output, and their bodies are designed to accommodate these power and heat outputs.

Important points to consider regarding blow dryers used by professional hairdressers for fast and effective results:

• The desired blow-drying results can be achieved with blow dryers of 2000 watts or more. The numbers printed on the blow dryers are usually the model name or series name, and the highest-powered blow dryer is 2500 watts.
• Don't fall into the trap of thinking that the most expensive is best, or the cheapest is most useful. Avoid products from countries that manufacture in environments that disregard human dignity and labor.
• Cable length is important. Professional machines have a total length of 3 meters, including the product.
• Choose a product based on your hair texture. For fine and short hair, 2000 or 2300 watts are sufficient, while for thick, coarse, and challenging hair, you should choose 2500 watts.
• Professional machines have two nozzles, one short and the other wide.
• It is important that the blow dryer you buy is of good quality in order to avoid undesirable results.
