I bought this for my daughter who has long hair, wears extensions and flat irons her hair everyday. She wears expensive extensions and flat iron was ruining them because she went over and over same strand with iron. Now that she uses tresseme's she only goes over strand once, her hair is so shiny and soft, no sticky residue . she thanks me everyday for saving her hair. Thanks tresseme

I bought this product a few months ago, and love it! I flat iron my hair every day and noticed a big difference ever since I starting using this spray. My hair straightens faster, no need to go over strands more then once and my hair feels softer and less brittle. A few spritz go a long way with this product!

Love this heat spray! When I style my hair with heating tools I always use a protective spray and I have to say, for me, tresemme makes the best ones. And this one is no exception!

I am a lover of all TRESemme products. This TRESemme Keratin Smooth Flat Iron Smoothing Spray works very well. I spritz a generous amount on my hair right before I straighten my hair with my flat iron and it seems like it protects my hair.

This is an absolute must-have for flat-ironing your hair! Leaves your hair touchably soft, doesn't weigh it down, protects hair from the high-heat of styling tools and smells really wonderful (doesn't leave a 'burnt' smell in your hair like some product does). The spray bottle format ensures all hair is coated without having to use a large amount of product. Great buy!

I have curly haïr. When i whant them flat i use Treseme Keratin smooth Iron flatening spray because it is effective. I still have difficultés whith humidity though. So i flaten when it's dry out. I would like to chalenge all compagnies to create à production that would take humidity in consideration to have beautiful flat haïr in any weather.

This is the best drug store flat iron smoothing spray I have ever purchased. It is just as good as the more expensive salon sprays. I use it all the time and it keeps my hair silky straight all day.

This helps keep my hair soft, smooth, shiny and protected from damaging heat styling. It doesn't weigh my hair down or make it feel greasy. Would definitely recommend to friends.

My mom has this at home and I tried it out when I was straight ironing my hair. I love the smell and it made my hair so shiny, and healthy looking. I like that it did not weigh my hair down and did not make my hair look greasy, I am going to get my own bottle since I am a flat iron addict.

I used this product on my hair extensions, when I wanted to straighten them and it help preserve them longer. It prevents damage due to heat and doesn't weight dow the hair!
