I used the Tresemme Keratiin Smooth Keratin Infusing serum on my hair and I was very impressed at its smoothing properties! I was able to straighten my normally curly hair, with little frizz! Very satisfied!

Surprisingly really liked this. I thought it weigh down my hair or make it oily and it did neither. It smells greats and makes your hair look less frizzy and more shiny :)

This actually worked for me. It didn't make my hair greasy or heavy or anything. It noticeably reduced frizz in my hair, and it is so easy to work into your hair. It made my hair noticeably smoother, and it makes your hair smell amazing!

I bought this at Shoppers Drug Mart at a super amazing deal, so the price is great. I might buy this product again.

The best serum out there for a sleek and smoother healthy hair I have thick heavy bleached hair and when you see it or touch it it's a silky hair try it out

WOW!!! I got the bottle where its clear and you can see the oil. I believe it is the same product but ANYWAYS, I literally felt a difference after one use. I use this in conjunction with the 7 day smooth system heat activated treatment and the split remedy leave in split end conditioning treatment. my hair feels so damn smooth and shiny. HOLY GRAIL.

I have tried this serum in a small travel sized sample. I have naturally curly hair but do straighten it often. I applied it before straightening to prevent the frizzies and hopefully add shine to my hair. I only use a small amount cause too much and it takes forever to wash out of my hair. It does provide shine, but I found I like my usual brand better and it controls my frizz longer with natural ingredients.

La kératine est un élément vraiment important pour les cheveux et ce produit de TRESemmé est formidable pour nourrir les cheveux et faire disparaître les frisottis, surtout présents l'été avec l'humidité. Il apporte douceur aux cheveux et j'aime en ajouter entre les shampoings sur mes cheveux car je trouve que cela protège du soleil et garde les cheveux en santé. Une toute petite quantité de produit suffit et la chevelure est nourrit et brillante.

Amazing for smoothing fly aways and heat damaged hair. My hair can get really dry and this serum is a great way to restore moisture without my hair getting greasy or weighed down. Love Tresemme because they don't test on animals!

this is an amazing product for calming down the frizzies and I;m sure as the warm weather and humidity near I will be using it more. The key is to not use A little goes a long way and too much leaves my hair looking like I havent washed it in a week .TOO MUCH

This serum worked great on my thick curly hair. I love that it calms it down and really helps to minimize the frizz factor. first time i put too much on and it felt greasy, second time i put 1/2 the amount and it made a difference. love the scent too.
