I have used this product almost since released. I use it almost every morning before drying and straightening and have found a significant difference in my (fine) hair strength and smoothness than without. It is supposed to be 7 days smooth, but I don't go that long without washing, so I cannot say... Still recommend trying for all hair types and situations!

My hair hates Tresemme. Everytime I get a sample it's with renewed hope only to be let down. This left my hair greasy and limp.

I have short hair, so maybe it would work better on long hair. I also found the smell to be off-putting.

First and foremost, I've always loved TRESemmé's Heat Tamer Spray, so I had high expectations when using the TRESemmé Keratin Smooth System Heat Activated Treatment. Now, this product claims to transform unruly hair into salon-smooth hair that even lasts for one week or up to 3 washes. The directions are to first wash with their shampoo and conditioner (note: I do not use the first 2 steps of TRESemme's 3 step system), apply approx. 8-10 pumps, blow dry, and flat iron. In my opinion, I think that applying 8-10 pumps is a little excessive as one bottle only comes with 88mL. Not only that, but it literally drowns your hair in product and weighs it down. Personally, I use 2-3 pumps, applying to the ends and working my way up. Right off the bat, I love the smell of this product. If their shampoo and conditioner smell like this, I would consider using it. The product isn't sticky. It applies like a leave-in conditioner. Next, I let my hair air dry to avoid any additional heat damage, but will regularly style my hair with a flat iron or curling wand the morning after. Naturally, my hair is thick and more or less "straight", but I'll still straighten it for that sleek straight appearance. It is coarse, but not frizzy. After straightening my hair, my hair is softer, smoother and shinier, but I say that with a bit of skepticism as I think it's hard to pinpoint specifically whether it made a difference in my opinion. Generally when I straighten my hair, I get softer, smoother hair anyways. For me, it's a bit hard to make a comparison because I recently cut off all my dead hair (over 10 inches). Overall, I would say, don't expect a miracle worker, but if you have frizzy, unruly, hair or damaged hair, you will likely see some sort of results after long term use. One bottle will likely last you up to one month with regular use, unfortunately, as a small amount of product does not go a long way. I would repurchase it in the future as I don't currently use any other heat treatment products, and because this stuff truly does smell amazing.

This product did not do well for my hair at all. Perhaps my hair isnt curly enough to require this smooth product? I have very fine and thin hair so it made my hair feel full of product. Wont be buying again- and will probably give this bottle away to my sister

I wanted to like this so much but my hair didn't like this one bit. It made my hair super heavy and kind of greasy for some reason. The value is really good, and TRESemme always has great products but maybe for a different hair texture than mine!

Je cherchais dernièrement un produit pour mes cheveux, car depuis un moment quand je les aplati, ils ne sont plus aussi beaux qu'avant. Ils ont l'air vraiment sec et les pointes ne sont pas belles du tout. Je suis tombé sur ce produit à la pharmacie, par hasard et je me suis dit pourquoi pas l'essayer, surtout qu'il était en spécial. J'ai été impressionné dès la première utilisation et c'est comme ça à chaque fois, mes cheveux sont moins rebelles et semble plus plat que jamais. Ils sont redevenus agréable à toucher, ce qui n'arrivait plus depuis un moment déjà.

I have thick, curly hair and I use TRESemmé Keratin Smooth Treatment any time I want to straighten my hair. I have to use more pumps than the directions suggest because my hair is so thick and long, but the bottle still lasts me a long time. I find that my hair is easier to straighten, takes less time to complete, and is very smooth when I use this treatment. I would definitely recommend it to anyone who straightens their hair, especially if they have thick or curly hair.

This product is amazing. I have been looking for a good heat protector treatment and this by far has been the best one I've found so far. I recommend going out and buying this product ASAP.

Just weighed my hair down
yes it was shiny but heavy
Keratin in beauty products means PROTEIN - and too much protein can weigh fine to medium hair down

J'aime beaucoup la gamme Keratin Smooth de TRESemmé et j'utilise ce produit systématiquement lorsque je me sèche les cheveux au séchoir car il protège bien les cheveux, c'est comme s'il y avait un écran qui empêche que la chaleur soit trop intense et abîme nos cheveux. Cela leur donne également une belle brillance. J'aime vraiment utiliser ce produit sur mes cheveux.
