TRESemmé Keratin Smooth Serum is a pretty decent product. I have naturally oily hair and am reluctant at trying hair serums as they tend to make my hair very greasy, but this product does not contribute to that problem at all.

I use a lot of heat on my hair, it's fairly long and the ends tend to get fried after almost daily blow-drying & straightening. I used this product daily for a little over two weeks and noticed quite a difference in the texture of my hair. The ends became much healthier looking and my hair overall had a wonderful shine.

I also happen to like the smell of this stuff ;)

Overall, I would probably purchase this product again, and perhaps use it for a longer length of time and see the full benefits of it.

I love this brand!! I do have naturally wavy hair that I do straighten daily. I did find this product watery at first but you do not need alot. It did tame my frizz and kept my hair straight.

I love anything Tresemme. Their products never disappoint. The new smooth Keratin formula left my hair silky smooth without the use of a flat iron. I stayed that way for about 24 hours and then my natural waves took hold once again. But overall i really liked the product.

Love it! I have thin straight hair that is often dry at the ends and is prone to flyaways! This product works great. smooths out my hair and makes the ends look less dry and stops the flyaways.!

This is one of the best Tresemme products out there right now. It smoothes frizz effectively and lasts between shampoos. It can be used on wet or dry hair, which for me makes it a great on the go product. It has a nice smell and is great for any hair type.

This serum worked VERY well, especially after using it with the TRESemme shampoo and keratin smooth conditioner. It was well worth the price and it smelled great too!

I love the entire Keratin Smooth line from TRESemme. They are inexpensive but still offer salon-quality results. I've used this serum a few times I usually only use it if I've used the shampoo and conditioner. I try to always use the same product line on my hair at a given time - I feel it gives better results.
This stuff always makes my hair feel smooth and gives me a healthy shine without looking greasy or being weighed down. My hair had little or no frizz, also did not have to use my flat iron as much, just a few quick passes.
The only thing I don't really like about it is the smell, it's smells kind of boring and there is nothing special about it. I like my hair and my products to smell good.

Great product will continue to purchase to use for my whole family. Best Tresemme Keratin smooth Keratin infusing serum. I have tried others but I love this product.

I have very curly hair and I tried this serum on my hair . It left me hair very soft, and shiny. I was able to straighten my hair and no frizz. I will definitely buy this product again and again .

I use this product every day. Best value for your money. Not expensive and works great. I've tried them all. From salon products to grocery store. Get this..you need it
