I use this serum in my hair after every shower while my hair is still slightly damp. I have very thick hair and I feel that this product helps make my hair look straighter and shinier when it dries. My hair is also very long so I need 3 pumps to cover my hair although I do avoid putting it on my roots to prevent it from looking greasy. On certain days where my hair feels extremely dry I add a tiny bit to the ends which I find really helps make them look less damaged.

Has a nice fresh scent, you only need a small amount to cover shoulder length hair.its easy to comb through,and makes your hair smell nice and silky soft to the touch

This isn't bad but it's not great. It's a 'you get what you pay for' type of product. Low low price and does its job but nothing exceptional. It does leave my hair really soft though!

This serum works okay. Helps to keep my hair smooth and frizz free. It is non-greasy and hair does not look oily. Undecided as to whether I would purchase again, as there are other products I prefer.

I was able to sample this product a while back and I didn't mind it at all. It did a good job of smoothing out my hair and controlling the frizz. It lasted for most of the day and didn't leave a heavy buildup or greasy residue in my hair.

This product is just what I needed for my hair this Summer @TRESemmé (Keratin Smooth Keratin Infusing Serum) it help to eliminate frizz, but your hair keeps its bouncy and full look. It also makes your hair have incredible shine and a smooth look. Wonderful #TRESemmé Haircare. I personally endorse and love this product.

Awesome product! It helps eliminate frizz, and it makes the hair appear shinier ... and thus making it look healthy! I love how my hair feels after I use this product.

I was given a sample of this to try and it actually worked pretty good. It added that extra moisture and protection to my hair without leaving it oily or heavy feeling. It worked well at smoothing out my hair to give it the really sleek straight look and seemed to add some nice shine to it as well. I haven't purchased it yet as the price is a little more than what I like to pay.

Excellent value for money. For this kind of product I normally would go for high end brands but this one is a winner and my hair is really difficult to deal with, so this should work well with almost any hair type!

My hair does feel soft. I have very fine-thin hair and whenever I pick up a product, I make sure it doesn't weigh me down or leave a sticky feeling. I didn't feel sticky at all, this formula gets As across the board for me. Keratin is good to help cure frizz. I tend to use it before blow drying but if I need to keep down flyaways- I dab a little on my hair.
