This is not a diffuser, don't be fooled. It does not diffuse the air blowing from the dryer. I have naturally curly hair that curls well using a traditional diffuser attachment on my hair dryer. I was looking for something more portable for travel. This is not it. I held it 6" from my face to feel the air and it was really blowing. Then I did the same with my real diffuser and I could barely feel the air. That is how it should be. Curly girls want the heat not the blowing. Don't waste your money. It's very heavy too.
