Its a great spray for the price. A little goes a long way. If you use too much, I find it made my hair flat, as I have fine hair and that's easy to do. Just a light spray and comb through. My hair was left soft, and protected. Nice smell too.

I love this product. I stopped using heat on my hair because of breakage. Now on the occasions that I do flat iron my hair this works amazing. I only have to go over each section once and my hair is straight, soft and shiny. It lasts until my next shampoo. Really great product.

From someone who straightens their hair often- this works so well. I love the entire Keratin smooth line and feel like this helps my hair stay smooth and helps protect it. Definitely will be repurchasing. Love it!

By far the best product for hair that goes under flat iron on a regular basis...it keeps my hair from damage and makes it look fantastic... price is also decent and is available everywhere...whats not to love

I normally buy high end sprays to protect my hair when I straighten my hair but was on a budget and decided to try this out. I can honestly say it made my hair smooth and soft and I didn't have to go over the strands of hair several times while I was straightening and it didn't smell bad either. This might just be a go to from now on.

I use TRESemme Keratin Flat Iron Smoothing Spray every day when I straighten my hair, it makes the process so much easier on my hair and so much faster. Before I started using it it took a long time to straighten my hair because I had to go over every section so many times, my ends were split and my hair was very dry, now my hair is healthy, soft and shiny. I have tried some much more expensive flat iron sprays and they do not work any better than TRESemme which is only a fraction of the cost.

I have extremely thick hair as a result flat ironing it is a must , this heat spay makes my hair look and feel amazing . Ni frizzing like it usually dose . PERFECT spray for flat irons

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!
