I have pretty curly hair and I loved this dryer for diffusing my hair! It does operate at lower temperatures than other dryers I've used, but when I'm holding the dryer to my head it doesn't overheat and feel too hot on my scalp. With most dryers even the warm/medium heat can almost feel like it's burning my head, so the settings were perfect. Also, the end/barrel doesn't get hot so i can hold it while using the product and I love that. Overall it's a great dryer and I would definitely recommend it.
