I'm not sure why but I'm not into the TRESemme Keratin Smooth System Conditioner. I like the majority of TRESemme conditioners but this one is not for me. It doesn't feel like it makes my hair any smoother.

I liked this conditioner for my dry and frizzy hair. It made my hair feel so soft and smooth when in the shower and it smells really good. It helped to tame my frizz until my next wash which I really liked since I don't wash it too often because it's so dry. I'll probably buy this again in the future.

Pour un conditioner de magasin il est très bien efficace ne laisse pas les cheveux gras et il rend les cheveux doux et brillant pour le prix c'est bien

Works pretty good for being on the lower end (of drug store shampoos/conditioners) it left my hair soft and smooth with minimal frizzies. Overall I would give it a 4/5 stars.

I was very impressed with how well TRESemmé® Keratin Smooth System Conditioner moisturized my hair. It definitely reduced frizziness and improved its smoothness, helping me achieve a super straight hair look. I feel like it dramatically protects my hair from the heat damage I subject it to.

So this is bargain for your buck as the bottles are huge. I like the smell and have used this to help straighten my curly hair. I use the whole line. I find it helps and keeps the frizz under control.

Pour un produit si peu cher le résultat est incroyable. Il lisse mes cheveux fins sans les rendre lourd . L'odeur est divine et reste longtemps dans les cheveux.

I use the Tresemmé Keratin Smth System Conditioner since it's on the market and I love that conditioner. It's leave my hairs straight, fluffy without frizness. I use it along with the shampoo and the result are perfect. It might not last 7 days but my hair look good for at least 4 days!!! Great hair products!

I love the tresemme line as you get a lot of product for a great price. My hair really needs a silky conditioner and this one is great. A little product goes a long way. Will definitely purchase again

I like this conditioner. The keratin line from tresemme is actually pretty good. My hair felt nice and clean and there were absolutely no frizzy hairs sticking out which I sometimes get lol overall pretty decent :)
