My hair dresser recommended I get a diffuser because I have naturally curly hair and he knows how lazy I get to style my hair! Whenever I thought of a diffuser I thought of really big hair so I just kept saying yes I will look into it and never did! Then one day I think he got tired of hearing me complain about my hair, he said he would order one for me and let me know when it arrived. I wasn't very happy about it but I agreed and it costs almost as much as my hairdryer but nevertheless I took it. He showed me how to use it and I struggled at first but with a little practice I have become quite good! Now I can't live without it! I have used it on my daughter's hair as well and it is so quick and easy! My diffuser is quite big and has long prongs so it dries in half the time and it keeps my curls in tact. My daughter has thick long hair with a slight curl so all I do it blow out her fringe and the rest I dry using the diffuser on low heat and it gives he hair such a nice curl at the end! This would work for any length of hair and why fight frizzy hair - diffuse it! Work with what you have! Make it work and make the best of it! Most hairdryers come with the diffuser attachment but mine didn't so I had to buy one but it was money very well spent. Styling my hair has never been easier! It is so easy to use all you do is tilt your head and slowly position your hair on the diffuser, use your hair dryer on a low speed and hold for a couple of minutes until set. I would recommend using a heat styling product or curling product such as John Frieda's Dream Curls, Tony and Guy's Beach Curl's or mousse such as Taft or any similar product.
