This is one of the products I use from time to time to soften my hair. My hair can get dry and frizz from drying and straightening. Makes my hair feel like I just came out of the salon. Makes your hair come back to life. I recommend this product!

I didn't mind this at all. It's a little heavy and if you put too much in can leave your hair kind of greasy looking so stuck to the ends. It has a pleasant smell to it.

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.

My hair is usually frizzy and dull especially after blow drying it. Anyways, I saw this at Walmart near my place and decided to try it. It did it's job! My hair looked and felt frizz free as well as shiny and smooth. I like the smell too! I recommend it!

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!

At first i found the product more on the watery side then on the oily side. I'm so used to serums being oily & I guess that's what I expected. When I saw it was more watery I thought of great, what dos I waste my $ on now. I was wrong. The serum was great! Kept my hair in check and didn't frizz up which I certainly thought would happy! Great product and kept my hair soft! Smells nice 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.

I've tried do hard to love Tresemme products. So hard. I was hoping this serum would deliver the results of my salon grade serum so I could save a little coin but no luck. It would be better for someone with not so try hair or who uses a lot of tools and heat.

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 would say this is a decent product to control frizz and leave hair feeling smooth and give it a shine. I use the TRESemme Keratin Smooth Keratin Infusing Serum immediately after I wash my hair. With just a tiny amount, I rub the product onto the palms of my hands and run the serum through my hair from the middle to the ends. My hair overall looks and feels soft, smooth, and frizz-less.
