Est-ce que c'est vraiment efficace les produits protecteurs, je ne sais pas encore! Toutefois, je trouve que mes cheveux ont une plus belle texture avec ce produit qu'avec d'autres grandes marques.

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've used this a couple of times. I don't know if it really works or doesn't because I haven't realllyyy been able to notice a huge difference but my friend swears by it. One thing I noticed was that it definitely made my hair smell good post straightener (which smells bad), and it made my hair smooth to touch.

It works well, but I have to be careful not to use too much. As my hair is very fine and easily weighed down.
I have wavy hair, and it helps keep fly aways at bay.
It would work great with thick and curly hair.

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.

I have read some of the reviews so definitely check which hair type this might work best on. I have wavy hair that I straighten using a flat iron and I find that this works for me. It kept my hair smooth and didn't weigh it down.

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.

I purchased this product with the hope that it would work well in my 4a/c curly hair. No luck, although I blowed out my hair as normal I felt this product left my hair dry and brittle.

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.
