To start, I would like to say that I have had very long hair almost all my. I also have very thick and wavy hair, which makes it somewhat difficult to dry in a proper way after I wash it due to that it easily gets frizzy and tangled up. The Universal Hairdryer Nozzle from Red by Kiss is outstanding for my hair! I got this to get more volume on top, but I use it to straighten my hair also which is working wonders for my hair. They have a long and a short one and I bought the short which fits me perfectly. The nozzle is suppose to fit most hair dryers and I have a Con air dryer and when reading some of the reviews for this product I was convinced that it would work for my dryer so I placed the order and got it just 3 days after. I am so happy with the great fit! I highly recommend this nozzle! You will be happy while using this for your hair no matter if you have short, medium or long hair. This is one of the best deals ever! A true five star hair product! I can use this without any styling products added to my hair. I really like that a lot.
